Ignore the middle xd
But, the degrees are in degrees, radians are in radians, and there are also the sine, cosine, and tangent values, which you should remember

snowflake0531 · Answer

Of this, you can find 3pi/2
But, I suggest memorizing most of it

nettym · Answer

Ohh wow lol
So by looking at 3pi/2 im guessing its 0, bc x axis is cos which in the question its asking for cos?

snowflake0531 · Answer

._., find 2pi/3

nettym · Answer

At 270 degrees?
