Folks! I have recently come to the pleasures of Mathematica from other popular but very expensive programming methods that I, as a retiree, cannot afford. My specific question is this: why am I able to get Mathematica to do the complete integral of sin(x)/x, but it refuses to do any of the other types: specifically sin^3[x]/x or sin^3[x]/x^3 over the half interval from zero to infinity. (see page 449 of G & R Table of Integrals). It seems to suggest that throwing away my Gradshtein and Ryzhik is premature in spite of the claims in the Mathematica "Mathematics and Algorithms" manual.
