$\sin\left(x\right)\left(\cot\left(x\right)+\tan\left(x\right)\right)$
Learn how to solve integral calculus problems step by step online. Prove the trigonometric identity sin(x)(cot(x)+tan(x))=sec(x). Starting from the left-hand side (LHS) of the identity. Rewrite \cot\left(x\right)+\tan\left(x\right) in terms of sine an cosine. Multiply the fraction and term. Simplify the fraction \frac{\sin\left(x\right)}{\sin\left(x\right)\cos\left(x\right)} by \sin\left(x\right).
