$\cos\left(x\right)+\cos\left(x\right)\tan\left(x\right)=\sec\left(x\right)^2$
Learn how to solve differential calculus problems step by step online. Prove that (1+tan(x))cos(x)=sec(x)^2 is not an identity. Multiplying polynomials \cos\left(x\right) and 1+\tan\left(x\right). Applying the trigonometric identity: \tan\left(\theta \right)\cos\left(\theta \right) = \sin\left(\theta \right). Group the terms of the equation by moving the terms that have the variable x to the left side, and those that do not have it to the right side. Applying the secant identity: \displaystyle\sec\left(\theta\right)=\frac{1}{\cos\left(\theta\right)}.
