Learn how to solve trigonometric identities problems step by step online. Prove the trigonometric identity 1/cos(x)+(-cos(x))/(1+sin(x))=tan(x). 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}. Any expression multiplied by 1 is equal to itself.
