double cos(double t)
float _ncosf(float t)
Arguments
t radian angle
Return Value
The cosine of t
Description
Calculates the cosine of the specified argument using the following formula:
cos(t) = (t^0/0!) - (t^2/2!) + (t^4/4!) - (t^6/6!) +- ... t^(2n)/(2n)! cos(t) = 1 - t^2/2 + t^4 * (1/4! + t^2 * (-1/6! + t^2 * (1/8! +.....
