Learn how to solve proving trigonometric identities problems step by step online. Prove the trigonometric identity (sin(x)+cot(x))/(tan(x)+csc(x))=cos(x). 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 all terms into a single fraction with \sin\left(x\right) as common denominator.
