Homework Help Overview

The problem involves determining the convergence of the integral ##\int_{0}^{1}\frac{e^{-x}}{\sqrt{x}}dx## using the comparison theorem.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • Participants discuss potential comparisons for the integral, with one suggesting that ##e^{-x}## is bounded on the interval [0,1]. Another participant questions how this leads to a suitable comparison.

Discussion Status

The discussion is ongoing, with participants exploring different comparison strategies. Some guidance has been offered regarding the bounds of the function involved, but no consensus has been reached on the most effective comparison.

Contextual Notes

There appears to be uncertainty regarding the choice of comparison functions and the implications of the bounds of ##e^{-x}## on the convergence of the integral.

Hi tm5501987. Try using [ /tex] with a forward slash and no space. [tex]\int_{0}^{1}\frac{e^{-x}}{\sqrt{x}}dx[/tex]
[itex]e^{-x}[/itex] is bounded between 1 and 1/e on [0,1], right?
 
I am lost, not sure how that gets me to something I can compare to.
 
[itex]\int_{0}^{1}\frac{e^{-x}}{\sqrt{x}}dx \lt \int_{0}^{1}\frac{1}{\sqrt{x}}dx[/itex]. Not so?
 
Got it, thanks
