Learn how to solve trigonometric identities problems step by step online. Prove the trigonometric identity (sin(x)-sin(x)^3)/(cos(x)^2)=1/csc(x). section:I. Express the LHS in terms of sine and cosine and simplify. Start from the LHS (left-hand side). Factor the polynomial \sin\left(x\right)-\sin\left(x\right)^3 by it's greatest common factor (GCF): \sin\left(x\right). Apply the trigonometric identity: 1-\sin\left(\theta \right)^2=\cos\left(\theta \right)^2.
