$\cos\left(2x\right)^{3}$
Learn how to solve simplify trigonometric expressions problems step by step online. Simplify the trigonometric expression cos(2x)^2cos(2x). When multiplying exponents with same base you can add the exponents: \cos\left(2x\right)^2\cos\left(2x\right). Apply the trigonometric identity: \cos\left(2\theta \right)=\frac{2\tan\left(\theta \right)}{1+\tan\left(\theta \right)^2}. The power of a quotient is equal to the quotient of the power of the numerator and denominator: \displaystyle\left(\frac{a}{b}\right)^n=\frac{a^n}{b^n}. The power of a product is equal to the product of it's factors raised to the same power.
