Hello I need to do a variable substitution within an integral in several different ways. I need Mathematica to rearrange the integral with the new variable definition without solving it. The resulting integral will be variations of Euler function. After seeing the resulting integral, I need Mathematica to actually solve it for me (that is, Mathematica needs to recognize that it is an Euler function). Can this be done? Many thanks Ed
