I have a trig problem :-) Find the six sixth roots of -64.
Note that z= -64 is in rectangular form and in polar form it is z=64(cos pi + isin pi).
Write your roots in both polar and rectangular form.

step-by-step explanation:

descending order means to order the polynomials from the term with the largest exponent to the term with the smallest exponent.  

therefore, the correct answer is d.  

#12 the answer is the third option
