TRIGONOMETRY
I tried converting (0,3) myself, but I can't seem to get your answer. What am I doing wrong? b. (R, theta) R = sqrt(x^2 + y^2) R = sqrt(0^2 + 3^2) R = 3 theta = arctan y/x theta = arctan 3/0 theta = 1.249 = (3, 1.249)

TRIGONOMETRY
Aaah, so those are the formulas! I'll remember those. That helps so much! You're awesome! Thank you for not just giving me the answers. The point of a study guide is to study and know how to get to an answer. Usually people just give the answer without showing the proc...
