Class  Description 

DBeta 
This is the first order derivative function of the
Beta function w.r.t x, \({\partial \over \partial x} \mathrm{B}(x, y)\). 
DBetaRegularized 
This is the first order derivative function of the Regularized Incomplete Beta function,
BetaRegularized , w.r.t the upper limit, x. 
DErf 
This is the first order derivative function of the Error function,
Erf . 
Dfdx 
The first derivative is a measure of how a function changes as its input changes.

DGamma 
This is the first order derivative function of the Gamma function, \({d \mathrm{\Gamma}(x) \over dx}\).

DGaussian 
This is the first order derivative function of a
Gaussian function, \({d \mathrm{\phi}(x) \over dx}\). 
DPolynomial 
This is the first order derivative function of a
Polynomial , which, again, is a polynomial. 
FiniteDifference 
A finite difference (divided by a small increment) is an approximation of the derivative of a
function.
