Thread: I need to find the exact value of 5pi/12.

1. I need to find the exact value of 5pi/12.

How do I find it exactly? I think the answer is (Sqrt(2)+Sqrt6))/4

Not quite sure if that's it. I would like a detailed explaination if I was incorrect. Thank you in advance.

are you asking why $\sin\left(\frac{5\pi}{12}\right) = \frac{\sqrt{2} + \sqrt{6}}{4}$ ?
