* d internal + external
d() gives the partial derivative.
d(y,x) internal
It differentiate y with respect to x.
e.g. d(x^2,x) gives 2*x.
d(f(x),x) is the same as f'(x) .
e.g. d(sin(x),x) gives cos(x).
d(y, x, n) external
It gives the n-th order derivative of y with respect to an undefined
variable x.
e.g. d(sin(x),x,2) gives -sin(x).
See also: diff, f'(x), lim, inte, ninte.
