$\frac{2+\tan\left(x\right)^2}{\sec\left(x\right)^2}-1$
Learn how to solve trigonometric identities problems step by step online. Prove the trigonometric identity (2+tan(x)^2)/(sec(x)^2)-1=cos(x)^2. Starting from the left-hand side (LHS) of the identity. Applying the secant identity: \displaystyle\sec\left(\theta\right)=\frac{1}{\cos\left(\theta\right)}. Divide fractions \frac{2+\tan\left(x\right)^2}{\frac{1}{\cos\left(x\right)^2}} with Keep, Change, Flip: a\div \frac{b}{c}=\frac{a}{1}\div\frac{b}{c}=\frac{a}{1}\times\frac{c}{b}=\frac{a\cdot c}{b}. Multiply the single term \cos\left(x\right)^2 by each term of the polynomial \left(2+\tan\left(x\right)^2\right).
