Q. Simplify to a single trig function with no denominator.sin2θ⋅cot2θAnswer:
Express cot(θ): Express cot(θ) in terms of sin(θ) and cos(θ) as cot(θ)=sin(θ)cos(θ).
Substitute cot(θ): Substitute cot(θ) with sin(θ)cos(θ) in the given expression to get sin2θ⋅(sin(θ)cos(θ))2.
Simplify the expression: Simplify the expression by squaring the cot(θ) term to get sin2θ×(cos2θ/sin2θ).
Cancel out terms: Cancel out the sin2θ in the numerator with one of the sin2θ in the denominator to get cos2θ.
Recognize simplified form: Recognize that cos2(θ) is already a single trigonometric function with no denominator, which is the simplified form of the original expression.
