Homework Help: Pre-Calc : Find the Exact Value of the Expression

Posted by Phil-- HELP NEEDED ASAP on Friday, May 10, 2013 at 9:46am.

Find the exact value of the expression without a calculator:
sin(3π/4+5π/6)
I've done:
sin(9π/12 + 10π/12)
=sin(19π/12)

What do I do now? Im confused if that would just be the answer or what? Wouldnt the answer be numerical?
