Explain. Thanks!
from pythagorean relation: sin^2θ + cos^2θ = 1
1 + cot^2θ = csc^2θ
sin^2θ + cot^2θ + cos^2θ = (sin^2θ + cos^2θ) + cos^2θ
= 1 + cos^2θ
=csc^2θ. . . answer
because of the fact that tan(?) = sin(?)/cos(?) and csc(?) = a million/sin(?), the given expression = (sin²?)*(cos ?)*{(sin ?)/(cos ?)}*{a million/(sin ?)} This simplifies to = sin²? to that end the given one is sin²?
