$\sin\left(x\right)\tan\left(x\right)$
Learn how to solve trigonometric identities problems step by step online. Prove the trigonometric identity sec(x)-cos(x)=sin(x)tan(x). Starting from the right-hand side (RHS) of the identity. Applying the tangent identity: \displaystyle\tan\left(\theta\right)=\frac{\sin\left(\theta\right)}{\cos\left(\theta\right)}. Multiplying the fraction by \sin\left(x\right). When multiplying two powers that have the same base (\sin\left(x\right)), you can add the exponents.
