MATHEMATICA5 - How do I plot this?

  1. Oct 15, 2004 #1
    [tex] \int _1 ^{\infty} \frac{1}{x^{1.3}}dx [/tex]​

    I need to plot this integral and approximations with left and right endpoints using Mathematica. I've tried a google search to get some instructions... but nothing. Does anyone know how to do this?

    Thank you.

    Mathematica contains very detailed help internally.

    I'm a bit confused what you mean by plotting this integral though -- the result of this integral is just a number. Do you mean to plot the integrand?

    Oh, I mean the area under the graph of [tex] \frac{1}{x^{1.3}} [/tex]. Well, thanks for the tip.

    It says that Integral of 1/x^1.3 does not converge in that interval.

    The instruction given was Integrate[1/x^1.3, {x, 0, infinity}]

    And, the result given is:[tex]- \frac{3.33333}{x^{0.3}}[/tex]
