solve
tan(2)-3tan 2=0

Can you show us the work you've already done? Where would you begin to solve this problem?

We can't just give you the answer. It's against the rules of this site. You need to put some effort into it. We can tell you where you're going wrong, lead you in the right direction, but we won't do the work for you. This assignment was given to you to learn.

So show us your work, let's start there, and then we'll work our way up. :)
