Start by simplifying the left side of the identity: $\cos\left(x\right)\left(\tan\left(x\right)-\sec\left(-x\right)\right)$
$\cos\left(x\right)\left(\tan\left(x\right)-\sec\left(x\right)\right)=\sin\left(x\right)-1$

$\cos\left(x\right)\left(\tan\left(x\right)-\sec\left(x\right)\right)=\sin\left(x\right)-1$
Learn how to solve problems step by step online. Prove the trigonometric identity cos(x)(tan(x)-sec(-x))=sin(x)-1. Start by simplifying the left side of the identity: \cos\left(x\right)\left(\tan\left(x\right)-\sec\left(-x\right)\right). Starting from the left-hand side (LHS) of the identity. Multiply the single term \cos\left(x\right) by each term of the polynomial \left(\tan\left(x\right)-\sec\left(x\right)\right). Simplifying.
