Learn how to solve trigonometric identities problems step by step online. Prove the trigonometric identity (tan(x)+tan(y))/(cot(x)+cot(y))=tan(x)tan(y). section:I. Express the LHS in terms of sine and cosine and simplify. Start from the LHS (left-hand side). Rewrite \tan\left(y\right) in terms of sine and cosine. Combine fractions with different denominator using the formula: \displaystyle\frac{a}{b}+\frac{c}{d}=\frac{a\cdot d + b\cdot c}{b\cdot d}.
