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