$\cos\left(\frac{\pi }{2}-x\right)$
Learn how to solve proving trigonometric identities problems step by step online. Prove the trigonometric identity sin(x)=cos(pi/2-x). Starting from the right-hand side (RHS) of the identity. Using the cosine of a sum formula: \cos(\alpha\pm\beta)=\cos(\alpha)\cos(\beta)\mp\sin(\alpha)\sin(\beta), where angle \alpha equals \frac{\pi }{2}, and angle \beta equals x. The sine of \frac{\pi }{2} equals 1. The cosine of \frac{\pi }{2} equals 0.
