I would just like to wish everyone HAPPY HOLIDAYS!!! Hope everyone is having a great time off school! And HAPPY NEW YEAR!!
The time has come, a new unit gone by so fast, and a test in no time. What i think about this unit is that it was ok, we did not learn anything much but when we came to something that was hard that i did not understand, it slowly came to me! What i thought was cool was when this unit introduced that everything was bundled together and i did not have much problems. This unit is like pretty good, did not learn much because it was already introduced in earlier units. Also what i thought was cool was that f(x)=3x+1 is that it is the same as y=3x+1 but you get to find an ordered pair with the 1st one. GL HF on your test!
Hello every body
this unit talks about function and relations
We went through this unit very fast knowing that winter break is coming up and we only have a couple more units to go before we finish math. When I look back at all the new things we learned, there are a lot. But I noticed that most of the new things we learned are linked to things we've learned in the past. As we all know, math is the science of patterns.
Another month, another unit, another test. What a way to start our Christmas Break by having a test.
Welll another unit has been completed.
Well it's time for another test, and with another test is another reflective blog. Well this unit was functions and I'm apprehensive to say that it wasn't to bad. I don't want to regret saying that tomorrow. When you first look at it and it's very intimidating, but really the closer you look you can see that it's really a linear equation. Just instead of having a y you have f(x). Then it was time to substitute the numbers in for x which also wasn't too bad. Being taught the domain and range was a little tricky because first you have to remember which is which (domain=x, range=y). Also the concept of it going on forever or infinity. Once you understand the basics everything else comes more easily. I hope that the confidence I feel now is reflected on the test. I wish everyone goodluck tomorrow and study hard!!!=)
yess one more day of school then winter break.
in this unit we learned about functions and relations. domains and ranges.
hi everybody. its the time of day where we HAVE TO BLOG.. FOR THAT ONE MARK =). anywayz. what i think of this unit is very confusing, frustrating, and hard. i really didn't understand much about this unit. i had difficulties and felt as if i should give up BUT, i will not give up. i will be studing soon and hope that it'll do me some good. tomorrow is also the last day, BEST WISHES FOR EVERY ONE ON THE TEST. MAKE THE LUCK BE ON YOUR SIDE... HAPPPYY HOLLIDAYYY EVERYONE =).
Tomorrow is the last test of the year 2005 for pre-cal, wow the year went by so quickly. This unit is about functions and relations. I've learned lots of things in this unit such as functions, relations, domain, range and writing a new equation(example: f(x)=2x-2). I also learned how to write the range and the domain, for example the given range is (0,14). This means that the lowest point on the graph in the y-axis is zero and the highest is 14.Most of the things I've pretty much learned. Like the graph, table of content and an equation can tell you the all the same thing. Well good luck on the test tomorrow and may all of you people have a happy holiday=)
This unit about functions isn't so bad at all. The only that's confusing is questions about finding the domain and range of this kind of question:
Hello everyone, well jeez has this semester gone fast, just two more days till Christmas Break (yes!!!) and were already half way through one of the days. Well this unit was umm okay but definitely not one of my best, some things Mr K was talking about I was just like BLAH... But after some work I pretty much got it. The input, output thing was easy for me I caught on right away because it's just a new name for substituting then solving for x or whatever the variable is. That was probably my favorite thing in the unit because we've done it tons of times before. The domain and range was confusing to me at first, I understand it sort of now but it's alright. Well good luck on the test everyone.
I pretty much liked this unit this time around. I think it's because I got a pretty good mark on my rational expressions test, and it gave me that little push that I needed to keep me going, you know what I mean? I really like working with functions, when I know what I'm doing. I know I had problems with the analytical geometry unit, but working on this unit is also helping with my graphing and linear equation skills, which is always nice, because the exams are sneaking up on us. I think and hope that I do well on this test. It would be such a nice christmas present!
In todays class we basically focused on two problems. The first one was as follows: The are of a trapezoid is given by: A=1/2(B+b)h. A trapezoid is bounded by the lines y=1/2x+4, x=4, x=10, and the x-axis. Find it's area.
This unit was pretty much all new stuff and the ones that we already knew about.
Wow, what can I say? Six weeks have gone by, and within those six weeks we've done three units, our third one to be rapped up tomorrow. Meaning every two weeks we've been getting a unit test. : Insane difference than that of last year, ain't it? (to those who went to jr. high)
I was pretty interested in this unit, functions and relations. It seems as though I can understand the things being asked, not 100%, but close enough. I think I really come to like this unit. Everytime we are soon to finish a unit, I try to think of what kind of questions would be asked, which mainly consists of those being asked in class, and I feel confidence that I can do it.
Just some prepping, and reminders to keep me from making unseen mistakes, and I'm up for it! In addition to my confidence level, I got an extra bonus mark! -- at least... that's what I think. Too bad E.I takes too much time. I could soo use those extra bonus marks.
*Quick re-cap of a function;
- A function is a relation(usually an equation) in which no two ordered pairs have the same x-coordinate when graphed. One way to tell if a graph is a function is the vertical line test, which says if it is possible for a vertical line to meet a graph more than once, the graph is not a function, therefore making it a relation.
Best wishes everyone!, and I know it may be a day or two early, but happy holidays/winter break as well :)
Hello everyone. Today in class we got our Rational Expressions tests back. Then Mr.K went over a few questions that people had trouble with. Afterwards Mr.K put up some questions on the board to review on function notation are two of the questions that we were given.
Here's the new set of acrostics for you.
As you all know, we do not have homework this weekend - OH YEAH!!!! :) Unless you didn't finish the exercise in class today that is ...
Question 8) This noted that tha function is called a constant function, therefore all answers equal 3.
a. f(4) = 3 b. f(1) = 3 c. f(k) = 3
Today's class we wrote in our dictionary. Here are the notes just incase anyone wasn't in class:
Today we started a new unit, It is called function's and relations. We learned the definitions of these 2 new word's or what ever you would like to call them.
It's that time again, another test another unit over. All I can say is that our first unit was a great pre requisite for this unit. This unit for me was so-so in that I sometimes could not really follow along well and did not understand at first but after awhile of looking at it, I have sort of figured most things out and glad that I figured most of it or some of it before the test it feels like I'm king of the world ! This is all i have to say for this unit. GL, HF.
This unit was hard and easy in same time. But if you follow the step you should be ok. Because it’s easy to get lost in the question step. (Especially the signs.)
I've nothing really much to say about this unit. This unit is neither easy nor hard. We just had to apply what we have learnt from earlier units like simplifying fractions, factoring and stuff and use it to simplify rational expressions. I think I've did this unit before when I was still back in the Philippines when I was taking 1st year High School. It was complicated at first, but after lots of practices, it got a bit easier. The experience really helped me here.
This unit was really hard to follow. I got help from an other teacher because Mr. K was busy, and I kind of understand it better now. I hope I do good enough for the test. Most of the exercise questions were hard, same with the pre test, but I happen to get some right, and I got pretty close for some other questions. I enjoyed the questions that were adding and subtracting, those are easy, but it can get confusing at times. Then there’s multiplying and dividing which is okay…and again it gets hard sometimes. Well that’s all I have to say about this unit, I notice the blogs are getting shorter and shorter.
OK folks, as promised, I've got two excellent little review quizzes you can take to practice your skills. If you have trouble with any of the questions, copy it down and post it to the blog so you can work on it together as a class.
Here we go again, blogin for the unit test. Alot of the things thats on this unit is basically all the information that was covered earlier in the year; adding/subtracting fractions and multiplication. The new materials were dividing(multiplying by the resiprocal and the restrictions(the non-permissible numbers). Complex trinomial that needs facting is still kind of confusing I still get it. Hope everyone gets pass this one of the last test... I think. GOOD LUCK:D
this is one of the days where we have to study hard and get nervous for the unit test tomorrow. i hope everyone in my class is ready for the test tomorrow. study hard fellow class mates =). what i think about this unit is that i liked it more than "SLOPES" :) ... doesn't anyone agree with me!? i think "t-sa" agree's with me!! =) i liked learning about adding, subtracting, multipling, and dividing rational expressions because step 0: was to factor everything to the simpliest as we could and no doubt about it that i was excellent and loved factoring.. (most times) and it was great that i learned how to use some of my past learning to combine with rational expressions =). at one point i didn't know what in the world mr. k. was teaching the class, but the next day i caught up very fast, came in for help at lunch and now i think im about ready to do the test.
Every mark counts! This unit was just okay. Like usual, I still have problems with it. I absolutely HATE stating restrictions, I find it pointless. I had fun in class during this unit! Even though I'm not the best in math, I enjoy being in the class. (: I hope Mr. Kuropatwa's mouth gets better! So, I guess dentists can still scare me. ._. Okay, good luck to everyone on the test tomorrow! Happy Studying!
Well hello everyone, looks like it's test yime once again, jeez lou weez I don't like tests but what can we do. I think I'll do pretty good on this test, because it's not really new material. It's basically the whole factoring thing all over again. The only thing that screws me up on factoring is when I get my signs wrong, putting negatives instead of positives is never a good thing. My weak spot in this unit was factoring out a -1 it was confusing but nowI think I understand it. I also need to keep reminding myself to ALWAYS ALWAYS ALWAYS like Mr.K says State the restrictions.
I like this unit the best! I felt like I understood most of this unit because it mostly consisted of material we already learned previously. For example, Factoring, adding & subtracting fractions, multiplying and dividing fractions.
The test is tomorrow and who isn't ready for it? I thought it was today so I studied all night just to write in our dictionarys , but oh well. We basically are using the same rules and patterns in our first unit of factoring and putting them to use on different types of rational questions.
Well I was glad that this unit didn't really have any new matarial. Because I always liked fractoring so I think that I'll do ok. For me this unit was pretty good because I only had to learn how to solve fraction within fraction questions. The only part that I'm a little shakee on is the word problems and fraction within fraction questions. Other than that I'm good I hope that there's only one word problem on the test *cross fingers*
Alas the time has come when we must post our pre test weblog. This unit like all the units we've went through has sure come and gone by fairly quickly. It seemed like we learned a lot of new things in this unit but clarified by Mr. K, he says that we are only utilizing old lessons to solve more complicated equations.
when the first time I encounter this unit I thought I couldn't do it. When mr. k told us that "mathematics is the science of patterns", I remember the lessons that my teachers in the past years thought me. And I apply it on the problems that mr. k gave to us, then my answers were correct. As the day goes by I've learn a lot of things about this unit. And now, let's study for our test on friday. Don't forget the ALWAYS and NO because if you forget that you will be in a big trouble. Until here, see you next time. STUDY HARD and GOD BLESS everyone for the test on friday.
Before we start our pre-test
this unit there wasn't really much that was new. it was good kind of. well i'm reflecting on how the unit was and i think i did good. multiplying and dividing fractions are hard but i get most of it. on the pre-test we had today i did petty good. I think if i study over the time we have i should get it and hopefully this time I can pass my test. i don't really know what else to say so yes. and that is my reflective blog for this unit. until next time everyone. GOOD LUCK!
Oh boy, looks like only after two weeks we've come up to yet another unit test. Can' t do anything but get used to it, huh? I am not looking forward to this upcoming test. Nope nada nidoran ....... : (nidoran - pokemon? HAH) *cough..right. anyways ....
Wow, another test ! I can't believe it. We move faster and faster as time goes on, it's crazy! I'm really worried, because I know that I don't have a very high mark in the class, and I failed the last two tests. I must admit, it's really hard not to get discouraged, because, yikes. I am. I would go and ask for help, but unfortunately, I really don't ever have time. I need to stay focused. I want to keep studying and studying, but I also learned not to overwork myself. Yikes, I'm really lost. I mean, at the beginning of the unit, I liked what we were doing, but now, I'm not so sure. And every time I do a test, I feel good coming out of it, only to find out that I failed. I think I need to think up some new strategies. Any ideas?
