$\sec\left(\pi -x\right)$
Learn how to solve proving trigonometric identities problems step by step online. Prove the trigonometric identity sec(pi-x)=-sec(x). Starting from the left-hand side (LHS) of the identity. Rewrite \sec\left(\pi -x\right) in terms of sine and cosine. Use the trigonometric relation obtained from the unit circle: \cos\left(\pi -\theta \right) = -\cos\left(\theta \right). Applying the trigonometric identity: \displaystyle\sec\left(\theta\right)=\frac{1}{\cos\left(\theta\right)}.
