2. If sin < 0
The method I am choosing to discuss is trigonometric functions for sin, cos and tan. After doing
some research I found the easiest way to solve for these functions is using SOHCAHTOA. This
method seemed to good to be true but I put it to the test with the

Exercise 2
1. The formula S = C(1 + r)t models inflation, where
C = The value of today
r = The annual inflation rate
S = The inflated value t years from now
Use this formula to solve the following problem:
