Verify the following identity:
sin(θ)^2/(cos(θ)) = tan(θ) sin(θ)
Write tangent as sine/cosine:
sin(θ)^2/(cos(θ)) = ^?(sin(θ))/(cos(θ)) sin(θ)
sin(θ) ((sin(θ))/(cos(θ))) = sin(θ)^2/(cos(θ)):
sin(θ)^2/(cos(θ)) = ^?sin(θ)^2/(cos(θ))
The left hand side and right hand side are identical:
Answer: |(identity has been verified)
