$\sin\left(\theta\right)+\sin\left(\theta\right)\cot\left(\theta\right)^2$
Learn how to solve trigonometric identities problems step by step online. Prove the trigonometric identity sin(t)+sin(t)cot(t)^2=csc(t). Starting from the left-hand side (LHS) of the identity. Factor the polynomial \sin\left(\theta\right)+\sin\left(\theta\right)\cot\left(\theta\right)^2 by it's greatest common factor (GCF): \sin\left(\theta\right). Apply the trigonometric identity: 1+\cot\left(\theta \right)^2=\csc\left(\theta \right)^2, where x=\theta. Since \sin and \csc are opposite functions they cancel when multiplying.
