simplify so; = So how would I write the answer? I know that but is that the actually answer? It didn't ask me for cos of anything. It just said simplify. And will the changing to trick I used work? Thanks in advance for all of your help. I've gotten so much better at Math thanks to this forum. Sham

What do you think "simplify" means? It you have a complicated expression that turns out to be equal to a single number, then that number is as "simple" as you are going to get!
