You can solve for mu1: var('x, mu1, mu2, sigma') result=solve(exp((0.5/sigma)*(x-mu1)^2)==exp((0.5/sigma)*(x-mu2)^2),mu

I also think that it is a bug. SageMath does not send the assumptions to Maxima solver.

2020-12-03 08:46:47 +0200 commented question Why won't sage (maxima) factor the symbolic expression 2*a3 - 2*a6?

Just an information: I tried with Maxima (version 19.01.2x) itself (not in SageMath) and it factorizes correctly:

Enter: factor(2 * a3 - 2 * a6);

The output is: -2*(a6-a3)

2020-11-17 06:27:56 +0200 commented question Unknown installation error in Windows

SageMath started using Python 3 since its version 9.0. I hope you can solve this issue and use the latest versions but if you need to use SageMath urgently, you may want to try earlier versions.

2020-11-16 07:21:07 +0200 commented question Unknown installation error in Windows

Using the latest release is preferable but in this case, I would try with an earlier version of SageMath.

Did you try the methods given in https://doc.sagemath.org/html/en/tuto... ?

If yes, we need more details.

Jupyter environment is already installed with SageMath. If you installed SageMath 9.1, just click on "SageMath 9.1 Notebook" and it opens a Jupyter session in your internet browser. On the right, you will see "New". Press on it and select SageMath 9.1. Now you can run your commands. Also see this.

A native binary installer for Windows is available. Please visit the SageMath page and follow the download link.

Once installed, click on "SageMath X.x Notebook" and use the program in the Jupyter environment. This is the standard way of using.

2020-11-09 00:28:23 +0200 asked a question A frontend with 2D input and palettes

Do we have a frontend that supports two-dimensional input with or without command palettes?

Like declaring a fraction as $\frac{a+b}{b+c}$ instead of (a+b)/(b+c), or writing an integral by choosing the symbol from the palette and filling in the dummy arguments?

I have no complaints with Jupyter but this kind of frontend would be very useful especially for non-programmers.
