Coversine
From Freepedia
In trigonometry, the coversine, denoted cvs(x), of an angle is defined as one minus the sine of the angle:
- <math> \mathrm{cvs}\,x = 1 - \sin x.</math>
The derivative of the coversine is the negative of the cosine
- <math> \frac{d}{dx}\mathrm{cvs}\,x = -\cos{x}\,</math>
and the integral is
- <math>\int \mathrm{cvs}\, x \,dx = x + \cos{x} + C.</math>
Very few applications of this function exist, and it is generally only used to provide a co-function for the versine.
