Submultiple Angles

What are submultiple angles?

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

Numbers or angles like A/2, A/3, A/4, etc. are called submultiples of A.

The following are the sub-topics which deals with the trigonometrical ratio of submultiple angels A in terms of A/2,trigonometrical ratio of submultiple angels A in terms of A/3 and trigonometric ratios of the angle A/2 in terms of cos A.
