# MATHEMATICA5 - How do I plot this?

$$\int _1 ^{\infty} \frac{1}{x^{1.3}}dx$$​

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 $$\frac{1}{x^{1.3}}$$. 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:$$- \frac{3.33333}{x^{0.3}}$$
