$\sqrt{\cot\left(x\right)^2+1}$
Learn how to solve simplify trigonometric expressions problems step by step online. Simplify the trigonometric expression ((cos(x)^2)/(sin(x)^2)+1)^1/2. Applying the cotangent identity: \displaystyle\cot\left(\theta\right)=\frac{\cos\left(\theta\right)}{\sin\left(\theta\right)}. Apply the trigonometric identity: 1+\cot\left(\theta \right)^2=\csc\left(\theta \right)^2. Cancel exponents 2 and \frac{1}{2}.
