Learn how to solve trigonometric identities problems step by step online. Prove the trigonometric identity sin(x)/cos(x)+cos(x)/(1+sin(x))=sec(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}. Multiply the single term \sin\left(x\right) by each term of the polynomial \left(1+\sin\left(x\right)\right).
