A point starts at the location (2,0)and moves counter-clockwise along a circular path with a radius of 2 units that is centered at the origin of an x-y plane. An angle with its vertex at the circle's center has a measure of θ radians and subtends the path the point travels. Let x represent the point's x-coordinate. (Draw a diagram of this to make sure you understand the context!) Complete the following statements.

As θ varies from 0 to π/2, x varies from  to  units.

As θ varies from π/2 to π, x varies from  to  units.

As θ varies from π to 3π/2, x varies from  to  units.

As θ varies from 3π/2 to 2π, x varies from  to  units.
