it says solve the system of equations on the polar plane: then it has those two equations. And says Write your solutions as polar coordinates [hint there are 4]

Ah, it's already in polar coordinates. (r, theta)

sin t = 0 when t = 0, pi ,

cantorset Group TitleBest ResponseYou've already chosen the best response.0
1 2 cos t = 0 when cos t = 1/2 , when t = pi/3, 5pi/3
 3 years ago

cantorset Group TitleBest ResponseYou've already chosen the best response.0
so the solutions are t = { 0, pi, pi/3, 5pi/3}
