Question

What quadrant does angle -7, in radians, lie?

Answer 1

Q IV

Explanation:

Well there are `2pi~~6.28` radians in a full circle.

So each quadrant has `(2pi)/4=pi/2~~1.57` radians.

Let's divide `-7/(pi/2)~~-4.45` Quadrants, so it is all the way around the circle clockwise and then about half way through the IV Quadrant.
