Defining constants after solving ODE/PDE
Solving the differential equation $f'(x) = f(x)$ the answer leads to $f(x) = ce^x$ where $c$ is a constant. How can I generically solve this ODE in SAGE and define $c$ afterwards (I don't want to use
Consider this script
x = var('x') f = function('f',x) f = desolve(diff(f,x) == f(x), f, ival=x) print str(f(x)) >> ce^x #I want to define c afterwards
A method I found:
#continue the previous prompt f(x,c) = f(x) h(x) = f(x,10)
Is there something else that I can do?
