Double angle formula calculator

Omni's double angle calculator is here to introduce you to the trig identities involving double angles.

Knowing how to calculate the double angle identities will help you with countless problems after your first encounter with trigonometry. From high school to university, and even after, this handy tool will give you the help you need, refreshing or calculating these critical mathematical formulas. With this tool, you will learn the following:. Double angle identities are a class of trigonometric identities that is, an equality that relates two mathematical formulas , being valid for all the values in a given range which equate the value of a trigonometric function for twice the value of an angle to an algebraic combination of other trigonometric functions applied to the value of the angle. This class of identities is a particular case of the compound angle identities , which allow you to calculate the trigonometric functions of sums of angles. In this section, we will learn how to calculate the double angle identities for the three fundamental trigonometric functions sine, cosine, and tangent.
