WebbThat's just circle geometry combined with SOHCAHTOA, remembering that the radius of the circle is 1. When the angle is 0° the opposite tip of the hypotenuse is at coordinates (1, 0) so we know that cos 0° must be 1 and sin 0° must be 0; when the angle is 90° the tip of the hypotenuse is at (0, 1) so cos 90° must be 0 and sin 90° must be one.
