Learn how to solve problems step by step online. (cot(x)^2)/(csc(x)^2+1)=(csc(x)-1)/(csc(x)+1). Wenden Sie die Formel an: \frac{a}{b}=\frac{c}{f}\to af=bc, wobei a=\cot\left(x\right)^2, b=\csc\left(x\right)^2+1, c=\csc\left(x\right)-1 und f=\csc\left(x\right)+1. Wenden Sie die Formel an: x\left(a+b\right)=xa+xb, wobei a=\csc\left(x\right), b=1, x=\cot\left(x\right)^2 und a+b=\csc\left(x\right)+1. Applying the trigonometric identity: \cot\left(\theta \right)^2 = \csc\left(\theta \right)^2-1. Applying the trigonometric identity: \cot\left(\theta \right)^2 = \csc\left(\theta \right)^2-1.
