The Trigonometric Double Angle identities or Trig Double identities actually deals with the double angle of the trigonometric functions. For instance,
Double Angle identities are a special case of trig identities where the double angle is obtained by adding 2 different angles. In this article, we will cover up the different aspects of Trig Double Identities. Before Double, You must have an understanding of Trig Basic Identities.
Trig Double Identities – Trigonometric Double Angle Identities
Here are some of the formulas which are expressing the trigonometric double angled identities in terms of angle x.
|Cos(2x)||=||Cosˆ2x – Sinˆ2x|
|=||1- 2sinˆx 1|
