$\left(1-\cos\left(x\right)\right)^2+2\cot\left(x\right)\sin\left(x\right)$
Learn how to solve differential calculus problems step by step online. Prove the trigonometric identity (1-cos(x))^2+2cot(x)sin(x)=1+cos(x)^2. Starting from the left-hand side (LHS) of the identity. Applying the trigonometric identity: \cot\left(\theta \right) = \frac{\cos\left(\theta \right)}{\sin\left(\theta \right)}. Multiplying the fraction by \sin\left(x\right). Simplify the fraction \frac{2\cos\left(x\right)\sin\left(x\right)}{\sin\left(x\right)} by \sin\left(x\right).
