Re: [sympy] Sympy.physics.mechanics / dynamicsymbols

Dear Jason, Thanks a lot for your explanation! Clear! I checked on metaclasses, but I must admit I mostly understood, that a simple user like me should not mess with them! :-)) Peter On Sun 6. Feb 2022 at 07:49 Jason Moore wrote: > Peter, > > All `dynamicsymbols` is, is: > > f = Function('f')

Re: [sympy] Sympy.physics.mechanics / dynamicsymbols

Peter, All `dynamicsymbols` is, is: f = Function('f') t = symbols('t') f_of_t = f(t) The last line `f(t)` is generating a new class of type f, instead of using a predefined class (look up metaclasses). So the user, typically not aware of this element in Python, is confused about what they are wo

[sympy] Sympy.physics.mechanics / dynamicsymbols

My question is more for my ‚general education‘ in sympy. I write this little program *from sympy.physics.mechanics import ** *import sympy as sm* *a = dynamicsymbols(‚a‘)* *b = sm.symbols(‚b‘)* *print(‚type of a:‘, type(a))* *print(‚type of b:‘, type(b))* I get this result: *type of a: a* *t

Re: [sympy] Bode_plot of transfer functions has ferqueny indicated in Hz but should be rad/s?

Hi, This is not an error, per se, as the frequency is needed to be plotted in Hz at times. Although I suppose there should be an option to allow both Hz and rad/sec for frequency, and rad / deg for phase. It is up to the user which one to choose. If you know how to allow both, using an optional ar
