$\sin\left(x\right)^2$
Learn how to solve equations problems step by step online. Prove the trigonometric identity sin(x)^2=1-cos(x)^2. 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. Since we have reached the expression of our goal, we have proven the identity.
