And then we can take all of this relationship and manipulate it in different ways. We will describe a geometrical way to create the graph, using the unit circle.This is the circle of radius 1 in the xy-plane consisting of all points (x, y) which satisfy the equation x 2 + y 2 = 1. Express theta in radians.

(But note that when you say that an angle has a measure of, say, 2 radians, you are talking about how wide the angle is opened (just like when you use degrees);. The time taken is t = 0.50 s. It helps if one recognises the lengths 3 and # sqrt2# as being two of the sides in one of the special triangle, namely 30°, 60° 90°.

The resulting angle is coterminal with the original angle. Have a look at the unit circle and you'll see that the x coordinates are negative here. A full revolution (360°) (360°) equals 2 π 2 π radians.
