comment Incorrect result from Integrate
@MichaelE2 good points about branch cuts. But I have thought the math/computer expert folks have decided on these things long time ago (PrincipalValue?) else one CAS will give one result, depending on its choice, and another will give different result for same problem because it decided to go another path (as it seems in this case). Any way, will have to learn more about these things myself one day. Good observations, thank you.

Sure. So both Maple and Mathematica are wrong. For some reason, now I feel a little better :)

comment Incorrect result from Integrate
Something is wrong. I tried this on Maple, with no assumptions. Mathematica and Maple gave the same numerical answer, except Mathematica made it imaginary (with minus sign), while Maple showed it as real (with positive sign). i.e. both gave 0.37 (in absolute terms). (again, no assumptions). So either Maple or Mathematica has a bug :) here is a screen shot: !Mathematica graphics

comment Plotting a graph
@user10366, just play with the PlotRange. Either use All, or give specific plot range. Will add small example. See help for syntax if not sure how. Notice, I used Frame->True, so plot range syntax is a little different.
