Find the complex fourth roots of 81(cos(3π/8)+isin(3π/8)).
a) Find the fourth root of 81.
b) Divide the angle in the problem by 4 to find the first argument.
c)Use the fact that adding 2π to the angle 3π/8 produces the same effective angle to generate the other three possible angle for the fourth roots.
d) Find all four of the fourth roots of 81(cos(3π/8)+isin(3π/8)). express your answer in polar form.
