$\frac{\cot\left(x\right)-\tan\left(x\right)}{\cot\left(x\right)+\tan\left(x\right)}$
Learn how to solve differential equations problems step by step online. Prove the trigonometric identity (cot(x)-tan(x))/(cot(x)+tan(x))=cos(2x). Starting from the left-hand side (LHS) of the identity. Applying the tangent identity: \displaystyle\tan\left(\theta\right)=\frac{\sin\left(\theta\right)}{\cos\left(\theta\right)}. Applying the trigonometric identity: \cot\left(\theta \right) = \frac{\cos\left(\theta \right)}{\sin\left(\theta \right)}. 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}.
