Finding the exact value of sin(15 degrees)
We will evaluate the exact value of sin(15 degrees), i.e. sin(pi/12)). We will first use the angle-difference formula for sine, then the half-angle formula for sine, and finally a 15-75-90 special triangle. This tutorial will help you with your trigonometry and precalculus classes! Shop my math t-shirts & hoodies on Amazon: 👉 https://amzn.to ...
