The point is moving around the unit circle.
The point travels 2π in 10 seconds: π/5 in one second.
The point starts at (cos 0, sin 0)
The location is given by
(cos (0 + πt/5), sin (0 + πt/5))
Mark M.
The last expression is the coordinates of the point at time "t."
To determine a specific time/location substitute the specific value for "t."
For example
At 2 seconds
(cos (0 + 2π/5), sin (0 + 2π/5))
(cos 2π/5, sin 2π/5)
(cos 1.25, sin 1.25)
(0.315, 0.949)
