Define multiple angle with an example

If A be a given angle then 2A, 3A, 4A, etc., are called multiple angles. Here we will derive the formulae for multiples of angles or numbers.

The following are the sub-topics which deals with the trigonometrical ratio of multiple angels such as trigonometric functions of 2A in terms of A, trigonometric ratios of 2A in terms of tan A and trigonometric ratios of angle 3A in terms of an angle A.
