INT - computes indefinite integrals of expressions containing unknown functions and their derivatives

Calling Sequences
 INT(E,x)

Parameters
 E - an expression containing unknown and known functions of the integration variable x.
 x - the variable with respect to which the integration is performed.


Remarks
-The differential oreder of the integrand is minimized.
-The form of the integrand can effect the integration procedure for rational expressions containing non-monomial terms in the denominator.  In such cases the result is always corect, though it may not be optimal.
