$\frac{1-\cos\left(4x\right)}{1+\cos\left(2x\right)}=0$
Learn how to solve equations problems step by step online. Find the roots of (1-cos(4x))/(1+cos(2x)). Find the roots of the equation using the Quadratic Formula. Multiply both sides of the equation by 1+\cos\left(2x\right). We need to isolate the dependent variable , we can do that by simultaneously subtracting 1 from both sides of the equation. Canceling terms on both sides.
