Best ResponseYou've already chosen the best response.0The important part is that they are 1/2 (both) and she told us to evaluate using the unit circle. :/

Best ResponseYou've already chosen the best response.0@misty1212 is right. The unit circle comes in either radians or degrees. (see second link I posted). If you use the radian version, you do not need to convert, and get the answer rightaway. However, at a certain point in our math career, we all have to know angles in both radians and degrees. Perhaps that's what the teacher intended to do... introduce the conversion between the two angle measures.
