Substituting function value in an expression
I have an expression like uR(t) == 3*iL(0) + uC(0)/2 - 4
how can I substitute for iL(0)
and uC(0)
, if I'm given, that iL(0) = 0
and uC(0) = 0
.
uR
, iL
, uC
are a functions of var t
:
t = var('t')
uR = function('uR', t)
iL = function('iL', t)
uC = function('uC', t)
thank you :)
