Learn how to solve trigonometric identities problems step by step online. Prove the trigonometric identity (1+sin(a))/1(1-sin(a))/cos(a)=cos(a). section:I. Express the LHS in terms of sine and cosine and simplify. Start from the LHS (left-hand side). Any expression divided by one (1) is equal to that same expression. Multiplying the fraction by 1+\sin\left(a\right).
