$\sec\left(a\right)-\cos\left(a\right)$
Learn how to solve proving trigonometric identities problems step by step online. Prove the trigonometric identity sin(a)tan(a)=sec(a)-cos(a). Starting from the right-hand side (RHS) of the identity. Applying the secant identity: \displaystyle\sec\left(\theta\right)=\frac{1}{\cos\left(\theta\right)}. Combine all terms into a single fraction with \cos\left(a\right) as common denominator. Apply the trigonometric identity: 1-\cos\left(\theta \right)^2=\sin\left(\theta \right)^2, where x=a.
