TODAY IN MATH

Today math completely sucked. It's always boring, and I think Mr. Z goes way to fast. I'm sure that if he slowed down a little, and elaborated more on things, kids would understand it. Anyways, we learned about how to add and subtract trig. functions. Like sine, cosine, and tangent. Basically you split the equation into two parts and work it out. You also have to change the degrees into like pie over two, or square root of two, over two. Really confusing and I have to understand it by next week. Another test! I just failed one, so I have to redo that, and now another one...?
