My question (MC 2 4th quiz problem 3)


This is a question on the fourth chapter of MC 2. I knew that A and B were both equal to sin120, so I didn't pick those. However, both C and D both aren't equal to sin(120), because C = cos(120) and D = sin(90) which are different, which the solution even pointed out.

Thanks for pointing this out. As written answer choice D should be accepted as it is not equal to sin(120) either.

We've updated the question to made answer choice D equal, so that answer choice C is the only one that is not equal. I've manually updated your grade on the quiz to accept your answer as it should have been accepted as well.
