Step-by-step Solution
Specify the solving method
Start by simplifying the right side of the identity: $\frac{\sin\left(2x\right)}{2\cos\left(x\right)^2}$
Starting from the right-hand side (RHS) of the identity

$\frac{\sin\left(x\right)+\tan\left(x\right)}{1+\cos\left(x\right)}=\tan\left(x\right)$
Learn how to solve trigonometric identities problems step by step online. Prove the trigonometric identity (sin(x)+tan(x))/(1+cos(x))=sin(2x)/(2cos(x)^2). Start by simplifying the right side of the identity: \frac{\sin\left(2x\right)}{2\cos\left(x\right)^2}. Starting from the right-hand side (RHS) of the identity. Since the expression on the right of the equality is too simple, it's not clear how we can proceed to prove the identity from there. Although we know that the identity is true.
