A point starts at the location ( – 5,0) 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!
a. Suppose the point has traveled for 0.1 seconds (t = 0.1). How many radians would need to be swept out from the 3-o'clock position [or from
(5, 0)] to get to the point's current position?
b. Write an expression in terms of t to represent how many radians would need to be swept out from the 3-o'clock position to get to the point's
current position.
d. Sketch a graph of g.
