OpenStudy (danjs):

Counter Clock wise is +

OpenStudy (anonymous):

would 3pi/2 be the positive coterminal angle?

OpenStudy (danjs):

you want to end on pi/2 where the arrows are pointing, terminal side

OpenStudy (danjs):

the trivial answer is +pi/2

OpenStudy (danjs):

if allowed

OpenStudy (danjs):

or yes, 2pi + pi/2, any multiple of 2pi added to pi/2

OpenStudy (anonymous):

well the answer choices are 3pi/2 ; - pi/2 pi/2 + 360degrees ; pi/2 - 360degrees 5pi/2 ; -pi/2 5pi/2 ; -3pi/2

OpenStudy (danjs):

how large is the negative clockwise angle? only one choice has the right one

OpenStudy (danjs):

-3pi/2 for the negative and pi/2 + 2pi = 5pi/2 for possitive
