Exercise
$\sin\left(x\right)+2\cos\left(x\right)^2=2\sin\left(x\right)-\cos\left(x\right)^2$
Step-by-step Solution
Learn how to solve problems step by step online. Solve the trigonometric equation sin(x)+2cos(x)^2=2sin(x)-cos(x)^2. Move everything to the left hand side of the equation. Combining like terms \sin\left(x\right) and -2\sin\left(x\right). Combining like terms 2\cos\left(x\right)^2 and \cos\left(x\right)^2. Applying the pythagorean identity: \cos^2(\theta)=1-\sin(\theta)^2.
Solve the trigonometric equation sin(x)+2cos(x)^2=2sin(x)-cos(x)^2
