This week in math class we continued with derivatives. What a surprise. But next Monday is our test, so I can see the light at the end of the tunnel! The new thing we learned this week were derivatives of inverse Trig Functions and derivatives of logarithms.
These were pretty nice because they were just more functions we would apply when solving. However, I was gone when we earned the logarithm one, so I will probably have to study that one extra. What I like about the derivatives of inverse trig functions is how sin is cos negated, tan is cot negated, and sec is csc negated. This will make remembering things easier.
As I said I like derivatives so far because you just plug numbers in. So sin^-1(36) would be 1/((1-36)^1/2). Similarly , ln(5) would just be 1/5. Although my favorite derive is definitely e^x which equals e^x. I may like it almost as much as the regular #s which when derived become 0.

Overall, I'm feeling pretty ready for the test monday. I just have to review some of the first things we learned, I would hate to forget the quotient rule… again. And of course I have to finish up my homework, because Procrastination man. Here's hoping all goes well and we can move on to a new subject.
