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