1: x squared y cubed z squared
2: x to the 4th power and z cubed
Answer:
<u> </u><u>-1 </u>
Step-by-step explanation:
Given that:
r = sin 2θ , θ = ± π/4 , ± 3π/4
Recall that:
x = r cosθ
y = r sinθ
The differential of y with respect to x


at θ = π/4 , r = sin π/2
r = 1

where;
θ = π/4




slope of the curve (dy/dx) at theta(θ) = pi/4 is -1
Number 4 is B and number 5 is A (sorry if it’s wrong)
