    How Do You Solve This PDE Using Separation of Variables?

    Meldraft: Thank you for your contribution. I agree and am also expecting boundary conditions... I want to carry on using the Fourier approach to solve An but due to the lack of boundary conditions, I find it impossible unless I miss something. I am not sure if the Eigen separation constant (λ)...

    Can Numerical Methods Solve an ODE Without Initial Conditions?

    meldraft: Your answer is correct and I wish to continue beyond the solution you stated. In this case by using a numerical method to plot the appromimate solution. JJacquelin: Thank you, and I have found a lot of sense from wha you told me. I have also plotted the curves and have a rough idea...

    Can Numerical Methods Solve an ODE Without Initial Conditions?

    I have to solve this ODE with numerical methods: (y^2 - 1)\frac{dy}{dx}=3y I have no initial conditions to solve it like you would normally do. I am hoping to use a numerical method (Euler... Runge Kutta) to approximate the solution. This is if I solve it using numerical methods right? So, I...

    How Do You Solve This PDE Using Separation of Variables?

    I have a battle with the following direct partial integration and separation of variables toffee: I have to solve, u(x,y)=\sum_{n=1}^{∞}A_n sin\lambda x sinh \lambda (b-y) If there were no boundary or initial conditions given, do I assume that λ is \frac{n\pi}{L} and do I then solve A_n...
