$\cos\left(x\right)\left(\sec\left(x\right)-\cos\left(x\right)\right)$
Learn how to solve trigonometric identities problems step by step online. Prove the trigonometric identity cos(x)(sec(x)-cos(x))=sin(x)^2. Starting from the left-hand side (LHS) of the identity. . When multiplying two powers that have the same base (\cos\left(x\right)), you can add the exponents. Since we have reached the expression of our goal, we have proven the identity.
