$\frac{\csc\left(y\right)^4-1}{\csc\left(y\right)^2-1}$
Learn how to solve simplify trigonometric expressions problems step by step online. Simplify the trigonometric expression (csc(y)^4-1)/(cot(y)^2). Applying the trigonometric identity: \cot\left(\theta \right)^2 = \csc\left(\theta \right)^2-1. Simplify \sqrt{\csc\left(y\right)^4} using the power of a power property: \left(a^m\right)^n=a^{m\cdot n}. In the expression, m equals 4 and n equals \frac{1}{2}. Calculate the power \sqrt{1}. Simplify \sqrt{\csc\left(y\right)^4} using the power of a power property: \left(a^m\right)^n=a^{m\cdot n}. In the expression, m equals 4 and n equals \frac{1}{2}.
