Hi, I'm writing a notebook to reproduce what I can see in this wikipedia page: https://it.wikipedia.org/wiki/Circuito_RC
The problem is the CAP 4, I'm looking forward to get the result that follow that text: dove K è una costante. Dunque: (latex folleow) {\displaystyle v_{C}(t)=v_{C}(0)e^{-{\frac {t}{\tau }}}+K\cos(\omega t+\theta )} This is my code, running in a colab notebook: # define the independent variable ‘t’ from sympy.abc import t import sympy as sp import math w = 2 * math.pi * 50 # define dependent variable in symbol form vc = sp.symbols('vc', cls=sp.Function) C, R, vo = sp.symbols('C R vo') cos = sp.cos diffeq = vc(t).diff(t) + (1/(R*C))*vc(t) - (vo*cos(w*t)/(R*C)) res = sp.dsolve(diffeq, ics={vc(0): 0}) res The result is really confused, compared to the nice wikipedia result. Is there a way to get the same result? (follow the latex) {\displaystyle v_{C}(t)=v_{C}(0)e^{-{\frac {t}{\tau }}}+K\cos(\omega t+\theta )} Thanks so much -- You received this message because you are subscribed to the Google Groups "sympy" group.
