[downloadnb-comparison] [05_complex_and_trig] SymPyDeprecationWarning in both RST and MYST

[shlff]

Good afternoon, @mmcky , I find a SymPyDeprecationWarning in both notebooks of MYST and RST and MYST-website lecture 05_complex_and_trig.

Please find a screenshot for the corresponding place of lecture 05_complex_and_trig (left: RST, right: MYST):

Do you think I should create a PR to manually fix this issue?

[mmcky]

@shlff does this show up in the html as well? Please submit a PR to fix if you can.

Yes, @mmcky . It also shows up in the html generated by md, and please see here: https://quantecon.github.io/lecture-python.myst/complex_and_trig.html

I will create a PR in this repo to fix it.
