$\sin\left(x\right)^2+\cos\left(x\right)^2$

Learn how to solve trigonometric identities problems step by step online. Prove the trigonometric identity sin(x)^2+cos(x)^2=1. Starting from the left-hand side (LHS) of the identity. Applying the pythagorean identity: \sin^2\left(\theta\right)+\cos^2\left(\theta\right)=1. Since we have reached the expression of our goal, we have proven the identity.
