Answer: f'(x) = - cos^2(sin(x^2))
Step-by-step explanation:
Derivative of:
f(x) = Sin^2(cos(x^2))
f'(x) = cos^2(-sin(x^2)
f'(x) = - cos^2(sin(x^2))
The diagram of each shape are shown below
The shapes that have two consecutive angles of 90° is square and rectangle, so the correct option is option A
