Learn how to solve trigonometric identities problems step by step online. Prove the trigonometric identity sin(x)/(1-cos(x))+(-(1+cos(x)))/sin(x)=0. section:I. Express the LHS in terms of sine and cosine and simplify. Start from the LHS (left-hand side). 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}. Simplify the product -(1+\cos\left(x\right)).
