Use your tables and substitution method. Tables can also be googled if you don't have the book.

For people who keep writing "with respect to what variable?" quit being fucktards, there's a high probability OP means x.
Anyway, use the identity sin^2 = (1-cos(2x))/2

That's no reason to condone sloppy problem statements. Besides, we're just preempting trolls.

you fucking fail for not seeing that this problem requires trigonometric identities.

You people really ARE retards. The symbol π is the real variable here. Aren't they finding new digits of π all the time? That sounds fairly variable to me!

I was just trolling you. When's the last time anybody claimed a constant is a variable because not all the digits were known? Expand your mind, doofus.
