complex algebraic function simplify - catlessness - Mar-12-2020 import sympy a=sympy.Symbol('a') C=sympy.Symbol('C') t=sympy.Symbol('t') E=sympy.Symbol('E') R1=sympy.Symbol('R1') R2=sympy.Symbol('R2') i=sympy.Symbol('i') i=E/(R1+1/(R2+a*i*t/(C-i))) res=sympy.solve(i,t) print(res)i dont have result from res, is it because i is on both sides of the equation? is there any other way to have a result of i=f(t) Thank you!!! RE: complex algebraic function simplify - Gribouillis - Mar-12-2020 Use an expression that must be zero in solve() as the docstrings says>>> import sympy >>> a, C, t, E, R1, R2, i = sympy.symbols("a, C, t, E, R1, R2, i") >>> a a >>> C C >>> z = i - E/(R1 + 1/(R2 + a * i * t / (C-i))) >>> sympy.solve(z, t) [(C - i)*(-E*R2 + R1*R2*i + i)/(a*i*(E - R1*i))] |
