$\frac{1+\cos\left(x\right)}{1-\cos\left(x\right)}$
Learn how to solve trigonometric identities problems step by step online. Prove the trigonometric identity (1+cos(x))/(1-cos(x))=(sec(x)+1)/(sec(x)-1). Starting from the left-hand side (LHS) of the identity. Divide the numerator and denominator by \cos(x). Expand both the numerator and denominator. Simplify the fraction \frac{-\cos\left(x\right)}{\cos\left(x\right)} by \cos\left(x\right).
