Learn how to solve trigonometric identities problems step by step online. Prove the trigonometric identity sec(a)^2+csc(a)^2=sec(a)^2+csc(a)^2. section:I. Express the LHS in terms of sine and cosine and simplify. Start from the LHS (left-hand side). Rewrite \sec\left(a\right) in terms of sine and cosine. Applying the cosecant identity: \displaystyle\csc\left(\theta\right)=\frac{1}{\sin\left(\theta\right)}.
