Hi, I'm not sure how I am doing this problem wrong and if someone could show me what is that I am doing wrong, that would be great!
Plot the point given in the polar coordinate, and find other polar coordinates (r, theta) of the point for which:
a. r>0, -2pi<theta<0, b. r<0, 0<theta<2pi, c. r>0, 2pi<4pi
(-3, -pi/4)
I know that for the first one you are supposed subract 2pi, for the second one replace with -r and add pi, and for the third add 2pi. I'm having a hard time finding the right answers.
For the a. I got -3, -7pi/4, for b. got 3, 3pi/4, and for c found -3, 9pi/4. The answers in my book got for a. (3, -5pi/4, b. -3, 7pi/4, and for c. (3, 11pi/4). Any help would be great!
