Learn how to solve simplify trigonometric expressions problems step by step online.
$\frac{\sin\left(x\right)^2}{\cos\left(x\right)^{1}}+\cos\left(x\right)^2=1$
Learn how to solve simplify trigonometric expressions problems step by step online. Solve the trigonometric equation tan(x)^2cos(x)+cos(x)^2=1. Simplify \tan\left(x\right)^2\cos\left(x\right) into by applying trigonometric identities. Any expression to the power of 1 is equal to that same expression. Move everything to the left hand side of the equation. Apply the trigonometric identity: -1+\cos\left(\theta \right)^2=-\sin\left(\theta \right)^2.
