$\frac{\tan\left(x\right)^2}{\tan\left(x\right)^2}+\frac{2\sin\left(x\right)^2}{\tan\left(x\right)^2}=1+\cos\left(x\right)^2$
Learn how to solve differential calculus problems step by step online. Prove that (tan(x)^2+2sin(x)^2)/(tan(x)^2)=1+cos(x)^2 is not an identity. Expand the fraction \frac{\tan\left(x\right)^2+2\sin\left(x\right)^2}{\tan\left(x\right)^2} into 2 simpler fractions with common denominator \tan\left(x\right)^2. Simplify the resulting fractions. There is no identity or mathematical rule that allows us to proceed trying to match both sides of the equality, so we conclude that it is not true.
