Dear Group,
Suppose I have a differential equation such as:
Eq(n^2*f(x) - x*Derivative(f(x), x) + (1 - 2*x)*Derivative(f(x), (x, 2)))
(Though typically more complicated)
and I want to replace the x variable - say x=cos(t)
Is there a way to make that substitution within SymPy and get back a
differential equation in t, as opposed to simply throwing the equation
to dsolve and hoping that it will solve it?
Likewise, is it possible to make a change of variable within an integral
without simply letting integrate loose on it?
David
