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