For what values of theta (0 less than or equal to theta less than or equal to 2) do maximum r-values occur on the graph the polar equation r = 2 sin4 theta? Note that the maximum r-value occurs at a point that is the maximum distance from the pole.

a. Pi/8, 3pi/8, 5pi/8, 7pi/8, 9pi/8, 11pi/8, 13pi/8, 15pi/8

b. 0 pi/4, pi/2, 3pi/4, pi, 5pi/4, 3pi/2, 7pi/4

c. Pi/8, 5pi/8, 9pi/8, 13pi/8

d. 0, pi/2, pi, 3pi/2

First step is to get rid of the square root. remember that a square root is the same as raising to the (1/2) power. see below: multiply exponents per exponent rules to get: remember you subtract exponents from the denominator and add exponents in the numerator so: simplify further: so a is the correct choice. if you don't understand this google exponent rules and it will you understand. look at the image results.
