$15\cos\left(x\right)^2+16\sin\left(x\right)^2$
Learn how to solve problems step by step online. Prove the trigonometric identity 15cos(x)^2+16sin(x)^2=15+sin(x)^2. Starting from the left-hand side (LHS) of the identity. Applying the pythagorean identity: \cos^2(\theta)=1-\sin(\theta)^2. Multiply the single term 15 by each term of the polynomial \left(1-\sin\left(x\right)^2\right). Simplifying.
