$3\cos\left(x\right)^2-\sin\left(x\right)^2$
Learn how to solve problems step by step online. Prove the trigonometric identity 3cos(x)^2-sin(x)^2=4cos(x)^2-1. Starting from the left-hand side (LHS) of the identity. Applying the trigonometric identity: \sin\left(\theta \right)^2 = 1-\cos\left(\theta \right)^2. Simplify the product -(1-\cos\left(x\right)^2). Multiply -1 times -1.
