I am having trouble with radians I cant seem to figure any of them out.

Can you explain it and show work please?

Thank you!!!

hw9: Problem 1 Pre Up Next 1 pt) For each angle below, determine the quadrant in which the terminal side of the angle is found and find the corresponding reference angle. NOTE 1: Enter \'1\' for quadrant I, \'2\' for quadrant II, 3\' for quadrant III, and \'4\' for quadrant IV] NOTE 2: You can enter as \'pi\' in your answers.] (a) -3 is found in quadrant (b) (c) = 1 is found in quadrant (d) -6 is found in quadrant and and = and -, is found in quadrant 17 and = Note: You can earn partial credit on this problem.

Solution

a) quadrant 4, reference angle = -(-/3) = /3

b) quadrant 4, reference angle = -(-/4) = /4

c) quadrant 2, reference angle = -(17/6 - 2) = /6

d)  quadrant 6, reference angle = 2- 6= 0.28
