## Thank you, I am sure this...

Thank you, I am sure this will work once I get the library properly installed

## error bar...

Yes, I had seen this in another post, but was not sure how to apply it to my list of data points and errors, or how to have it call my datafile for use.

## Re: Simply...

That is what I was afraid of...I knew it didn't have an exact analytical solution, but I thought it would give me some kind of integral I could solve numerically.  I can do a series solution, but I need 't' to be small and it doesn't like my use of '1/t.'

Yes this is a Friedmann-type vacuum solution from HOG.

## 2D Implicit Plot...

Thank you, I actually used a 2D Implicit plot. I typed the following function: 1=int(sqrt(x)/(exp((x-mu)/T)+1), x = 0 .. infinity) Then I right clicked on it, and the smartplot gave me the option of a 2D implicit plot [mu,T]. I wasn't sure if this was what I wanted, but after about 15 minutes, I received a plot of [mu,T]. As a check, I went back and used points from the plot to see if they gave me an solution of 1 for the integral. I found several confirmation points. I am not sure exactly how the 2D implicit plot works, but it seemed to do the trick. Please replace this text with the link to your file. The link can be found in the File Manager

## Thank you...

Thank you, That does work well. Now let's say I already know what numerical value I want the integral to equal. For example 1. And I want to know all the values of mu and T that satisfy the integral equaling 1. And I would like Maple to return a plot of all these values. Is this easy to do as well?
