A point starts at the location (-4,0) and moves CCW along a circle centered at (0,0) at a constant angular speed of 2 radians per second.

A point starts at the location (-4,0) and moves CCW along a circle centered at (0,0) at a constant angular speed of 2 radians per second. Let t represent the number of seconds since the point has swept out since it started moving. Draw a diagram of this to make sure you understand the context!
