Explanation:
that means it is the top vertex of the inscribed trigonometric triangle.
we assume the center of the circle is at the origin (0, 0).
so, the x-coordinate is then
cos(25°)×5 = 4.531538935... ≈ 4.532
the y-coordinate is then
sin(25°)×5 = 2.113091309... ≈ 2.113
remember, the basic trigonometric functions deliver these lengths inside the norm circle (radius = 1). for any other circle we need to multiply them by the actual radius.
the point on the circle at 25° is at
(4.532, 2.113)
