How do you find the value of sin 15?
An exact value for sin15∘… Add to your resource collection We will use the identity sin(x−y)=sinxcosy−sinycosx. We have that sin15∘=sin(45−30)∘=sin45∘cos30∘−cos45∘sin30∘=1√2√32−1√212=√2√32×2−√22×2=√6−√24. and so, since cosθ is positive between 0∘ and 90∘, cos15∘=√6+√24.
