$1-\tan\left(x\right)^2$
Learn how to solve product rule of differentiation problems step by step online. Prove the trigonometric identity 2-sec(x)^2=1-tan(x)^2. Starting from the right-hand side (RHS) of the identity. Applying the trigonometric identity: \tan\left(\theta \right)^2 = \sec\left(\theta \right)^2-1. Simplify the product -(\sec\left(x\right)^2-1). Multiply -1 times -1.
