Solved Trig Identity

Caption:

For this entry I thought it was important to include both a solved trig identity and the list of identities used. This makes it easier to follow what was going on. I chose this particular problem because there were a lot of steps involved. I was able to demonstrate multiple concepts in a single problem. I also liked this problem because you had to find a common denominator in order to solve it. When people get stumped when trying to solve trig identities this may very likely be their problem. Since it is a common mistake, I thought it would be a good idea to show how it should be done correctly.
