$\cos\left(a\right)^2\sec\left(a\right)^2$
Learn how to solve trigonometric identities problems step by step online. Prove the trigonometric identity cos(a)^2sec(a)^2=1. Starting from the left-hand side (LHS) of the identity. Applying the secant identity: \displaystyle\sec\left(\theta\right)=\frac{1}{\cos\left(\theta\right)}. Multiplying the fraction by \cos\left(a\right)^2. Simplify the fraction \frac{\cos\left(a\right)^2}{\cos\left(a\right)^2} by \cos\left(a\right)^2.
