$\frac{2+\tan\left(x\right)^2}{1+\tan\left(x\right)^2}-1$

Learn how to solve simplify trigonometric expressions problems step by step online. Simplify the trigonometric expression (2+tan(x)^2)/(sec(x)^2)-1. Applying the trigonometric identity: \sec\left(\theta \right)^2 = 1+\tan\left(\theta \right)^2. Combine all terms into a single fraction with 1+\tan\left(x\right)^2 as common denominator. Subtract the values 2 and -1. Cancel like terms \tan\left(x\right)^2 and -\tan\left(x\right)^2.
