Q. Simplify to a single trig function with no denominator.tanθ⋅cot2θAnswer:
Multiply and Simplify: Now, let's multiply tan(θ) by cot2(θ) using the definitions we've just recalled:tan(θ)⋅cot2(θ)=(sin(θ)/cos(θ))⋅(cos2(θ)/sin2(θ))
Cancel Common Terms: Next, we simplify the expression by canceling out common terms: (sin(θ)/cos(θ))⋅(cos2(θ)/sin2(θ))=sin(θ)⋅cos(θ)/sin2(θ)Here, cos(θ) in the numerator and one sin(θ) in the denominator cancel out:=cos(θ)/sin(θ)
Use Definition of cot(theta): The expression sin(θ)cos(θ) is the definition of cot(θ):sin(θ)cos(θ)=cot(θ)So, the simplified expression is cot(θ).
