If if sin(-x) = -sinx, does sin^2(-x) = -sin^2(x) or sin^2(x)

Question

question on precalc trig identities

sin(-x) = -sinx is an odd-even trig identity btw

Answer 1

To answer your question, sin^2(-x) is the same as (sin(-x))^2. Therefore, by your first identity, this identity is essentially (-sinx)(-sinx), which is sin^2(x).
