I have following expression
which is 1 solution of the ODE
ode2 := -(diff(y(t), t, t))+(4-12/(1+s*cosh(2*t))+(8*(-s^2+1))/(1+s*cosh(2*t))^2)*y(t) = 0
Now I wanted to construct 2 linear independent solutions via:
and calculate the Wronskian:
Determinant(Wronskian([f(t_b-t), f(t-t_a)], t))
Since I know these functions are solutions of the second order ODE which does not contain any first order derivative the Wronskian should be a constant. Unfortunately Maple has a hard time to simplify it since the epxression is a little big. Is it my fault or has anyone an idea what to do?
