Use trigonometric identities to simplify the expression.sin2(x)+sin2(x)cot2(x)

Sure, let's simplify the expression step by step.

Given expression is sin^2(x) + sin^2(x)cot^2(x)

Step 1: We know that cot^2(x) = cos^2(x)/sin^2(x). So, substitute cot^2(x) with cos^2(x)/sin^2(x) in the expression.

=> sin^2(x) + sin^2(x) * cos^2(x)/sin^2(x)

Step 2: sin^2(x) in the numerator and denominator will cancel out in the second term.

=> sin^2(x) + cos^2(x)

Step 3: We know that sin^2(x) + cos^2(x) = 1 (Pythagorean identity in trigonometry)

So, the simplified form of the given expression is 1.
