Hello All,
First, case changes to maxima have broken laplace, so that
laplace('DIFF(f(x),x),x,s) is not recognized,
but laplace('diff(f(x),x,s) is.
Second, I am using desolve to handle systems of equations. When it
encounters real roots, it returns
sinh and cosh instead of exponentials. It also works in terms of
function and derivative values at t=0.
For my problem it is much easier to work with exponentials and an
expression in the form of:
k1*exp(a*t)+k2*exp(b*t) as the solution of a second order equation.
Does anyone know a convenient
way of converting from the form returned from desolve, to the form
involving arbitrary constants?
