$\frac{\sin\left(x\right)^2}{\cos\left(x\right)}+\cos\left(x\right)$
Learn how to solve trigonometric identities problems step by step online. Prove the trigonometric identity (sin(x)^2)/cos(x)+cos(x)=sec(x). Starting from the left-hand side (LHS) of the identity. Combine all terms into a single fraction with \cos\left(x\right) as common denominator. When multiplying two powers that have the same base (\cos\left(x\right)), you can add the exponents. Applying the pythagorean identity: \sin^2\left(\theta\right)+\cos^2\left(\theta\right)=1.
