If you need publication quality plots look at Asymptote -
https://asymptote.sourceforge.io/
The only drawback to Asymptote is that it has it's own scripting
language. Look at the galleries of examples which also show the scripts
used. My favorite examples is -
https://asymptote.sourceforge.io/gallery/3Dwebgl/Klein.html
(it can be zoomed, rotated, and translated interactively with mouse)
with script -

There are a lot of different options. I suggest you start by looking
at these:
* Using the built in sympy plotting
(https://docs.sympy.org/latest/modules/plotting.html)
* Using the quite nice sympy plotting backend extension (
https://sympy-plot-backends.readthedocs.io/en/latest/overview.html)
* Combine your solutions with pandas (https://pandas.pydata.org/) and
tools for plotting and manipulation of pandas data. An example is
jupyter_Pandas_GUI
(https://jupyterphysscilab.github.io/jupyter_Pandas_GUI/Pandas_GUI_Doc_Home.html).
Note: I am the initial author of this last tool.

Good day, I am new in to sympy and it looks to be the suitable one
for my PhD. I have been working on my analytical work.
I now want try to plot and it seem not working for me. Can someone
guide me or help how to turn expression which include i-th term
and integral to change to numerical.
attached is sympy file.
Thank you.
