[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?  Warren

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

MATHEMATICA5  How do I plot this?
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]
