Consider a circle of radius 2 and a point P rotating around it. The angle θ, in radians, is given as a function of time t.
(a) What is the value of θ when t=1.5?
(b) Find the coordinates of P when t=1.5

You did not say what sort of a function so I must leave it general.
Theta = f(1.5)
x = 2 cos (f(1.5))
y = 2 sin (f(1.5))
