2010-11-23 · There's a pattern that you must memorize, which is the only way to do this. I will tell you that cos(30)= sqrt(3)/2. However, what I think you're asking is a way to actually work it out by writing down a mathematical expression, and unless you're can evaluate infinite term polynomials in your head, this just won't be possible.
