Learn how to solve simplify trigonometric expressions problems step by step online. Simplify the trigonometric expression (cot(x)^2cos(x)^2)/(cot(x)^2-cos(x)^2). Apply the trigonometric identity: \cot(x)=\frac{\cos(x)}{\sin(x)}. Multiplying the fraction by \cos\left(x\right)^2. Apply the trigonometric identity: \sin\left(\theta \right)=\sqrt{1-\cos\left(\theta \right)^2}. Cancel exponents \frac{1}{2} and 2.
Solving a math problem using different methods is important because it enhances understanding, encourages critical thinking, allows for multiple solutions, and develops problem-solving strategies. Read more
Simplification of trigonometric expressions consists of rewriting an expression with trigonometric functions in a simpler form. To perform this task, we usually use the most common trigonometric identities, and some algebra.
