I am using the ODE analyzer to look at the numerical solution to a second order ODE of the form 0=-uc'-kc+Ec" with u=.3, k=.0001 and E=10, and with conditions, c(0)=2 and c'(20,000)=0. When I try the solve numerically, I get an error message saying "unable to convert input to a first order system. Recieved error: too few boundary conditions, expected 5 got 2." What am I missing?
