TODAY IN MATH

Well, I'm in AP Calculus AB and today in class, we learned how to find the area of a shape on a xy axis. So you thought finding the area was hard in Geometry. (well kiddos... think again!) So, imagine a circle on an xy axis. It's equal and pretty simple but while having that circle on the xy axis, imagine that circle is made up with either squares or triangles. It will make the circle seem 3D. We are trying to find that area of that shape. To figure that out, you would need to find out the area of the shape that makes up the circle. Let's say this circle is made up of a lot of squares. We have to pin point out one square in the circle. (This isnt just squares place on the circle, think more 3D.) Since the area of a square is x squared, you would replace the x with the function that you solved for y. It would most likely be +/- the square root of a number minus x squared. (Yeah... don't feel bad that you might be lost... because believe, it's confusing stuff.) With that, you would just solve. :]

It is a whole lot easier with pictures and the examples she gives in class. Mrs. Corbett even has cool little geometrical wood shapes.

So that was what I learned in Math Class Today.
