I defined the following two integrals:



I2= 3*Integrate[f[3x],{x,0,q/3}]

and asked if they were equal


The result was returned unevaluated.  Why doesn't Mathematica (3.0 for
Windows (for students) and 3.0 for DEC) know that the two are equal?  Is
this result only true if q is real?  If so, is there a way to let
Mathematica know q is real and thereby return True?  If I issue the


or any of a variety of functions, Mathematica returns True.
