Answer 4

Okay, I got an answer: (9, 75 degrees+n*360 degrees) and (9, 75 degrees+(2n+1)*360 degrees), where "n" is an integer. Am I correct?

Answer 7

basically any coterminal angle to 75 degrees will work in place of 75 degrees

Answer 8

(9, 75 degrees+n*360 degrees) and (9, 75 degrees+(n+1)*360 degrees), where "n" is an integer.

Answer 9

so (9, 75+360n) works as part of the solution

Answer 10

Or is it just (9, 75 degrees+n*360 degrees) , where "n" is an integer?

Answer 11

it turns out that you could have r be negative, and just rotate in the complete opposite direction and still land in the same spot

Answer 12

if r = -9, then instead of rotating 75 degrees counterclockwise, you are really rotating 75+180 = 255 degrees counterclockwise (and going in reverse to end up pointing in the right direction)

Answer 13

so (-9, 255+360n) works too

Answer 14

where n is any integer
