The cosine of an angle is defined as the sine of the complementary angle. The complementary angle equals the given angle subtracted from a right angle, 90°. For instance, if the angle is 30°, then its complement is 60°. Generally, for any angle θ, cos θ = sin (90° – θ).

The cosine is the ratio of the base and hypotenuse. Then the value of the cosine of angle P will be q / r.

What is trigonometry?

The connection between the lengths and angles of a triangular shape is the subject of trigonometry.

The right-angle triangle PRQ is given in which angle R is a right angle.
