Scribing owns


Hello everyone!

As you can see, I'm making a post cuz I am the chosen scribe for the day. Math class today was a whole lot of fun. I've never been more absorbed in Math.. it was fun. To start out, we did four problems on the board involving right triangles and we needed to find the missing length. Well, the formula to find the missing side of a right triangle is a^2+b^2=c^2, which is also known as Pythagorean Theorem or Theory. Then, our beloved Math teacher Mr. K told us a story about Pythagoras. We learned that Pythagoras did not really make the the formula, it was only just an idea of Pythagoras. Let's say we have a triangle ABC,(wow, so imaginative on the letters). Side AB is 8 cm, and AC is 6 cm. We're looking for the hypotenuse, which is BC.

So, applying PT, 8^2+6^2=c^2. Oh, you have to find the square root of C. 8^2 is 64, 6^2 is 36, add them up and you get 100, which square root is 10. So side BC is 10 cm. Kinda useful, eh? (=
A more useful formula is the Distance Formula, which is a really useful. I can't quite explain it, but you can look at Mr. K's post below. It's really useful, as it can help you find the circumference of a circle and other stuff.

Oh, and for homework, we have to do Exercise 4, #1-20. *sigh*. :'(

And, finally, before I forget, the scribe for Monday is..... *drumroll please...*.... T-SA. (I know you're gonna hate me for this, but oh well. Life is never fair. (= )

HAVE A GOOD WEEKEND EVERYONE!
