Learn how to solve trigonometric identities problems step by step online. Prove the trigonometric identity (1-cos(x))/sin(x)=sin(x)/(1+cos(x)). section:I. Express the LHS in terms of sine and cosine and simplify. Start from the LHS (left-hand side). Multiply and divide the fraction \frac{1-\cos\left(x\right)}{\sin\left(x\right)} by the conjugate of it's numerator 1-\cos\left(x\right). Multiplying fractions \frac{1-\cos\left(x\right)}{\sin\left(x\right)} \times \frac{1+\cos\left(x\right)}{1+\cos\left(x\right)}.
