DESCRIPTION:
This video shows us an example problem in which we must use the sum formula for sine in order to evaluate a trig expression exactly. Keep in mind, there are multiple ways for us to break up 195 degrees. As long as you are able to break up an angle measure into two angles whose trig values you know, you should be able to get the correct exact value. (For example, you could split 195 into 150 and 45, both of which you could figure out the necessary trig values for.
