As mentioned in Trigonometric Identities a trigonometric equation that holds true for any angle is called a trigonometric identity. There are six trigonometric functions. Left sin x right 2 cdot left left cot x right 2 1 right sinx2 cotx2 1 cos pi cosp tan x tanx.
In mathematics a Fourier series ˈ f ʊr i eɪ-i ər is a periodic function composed of harmonically related sinusoids combined by a weighted summationWith appropriate weights one cycle or period of the summation can be made to approximate an arbitrary function in that interval or the entire function if it too is periodicAs such the summation is a synthesis of another function.
High School Math Solutions Trigonometry Calculator Trig Equations. For example any periodic processes can be represented as a sum of trigonometric functions Fourier series.
