$\left(1-\cos\left(x\right)^2\right)\left(1+\cos\left(x\right)^2\right)=1$
Learn how to solve sum rule of differentiation problems step by step online. Solve the trigonometric equation sin(x)^2(1+cos(x)^2)=1. Applying the trigonometric identity: \sin\left(\theta \right)^2 = 1-\cos\left(\theta \right)^2. Solve the product of difference of squares \left(1-\cos\left(x\right)^2\right)\left(1+\cos\left(x\right)^2\right). We need to isolate the dependent variable , we can do that by simultaneously subtracting 1 from both sides of the equation. Multiply both sides of the equation by -1.
