    First order, non linear ode problem

    Ok. I think I sort of got the hang of what is happening in this problem. Yeah, there is no other possibility except y(x)= 0 . It is the only solution that would work for the given IVP. Thanks,

    First order, non linear ode problem

    thanks for the detailed explanation. So I need to find the unique solution, and you have taken me to the part were i fail to find it. This is my blockade. The IVP is when y(0) = 0 and when i try to solve for "c" it is not possible. Uniqueness fails. I think this is what Dick was trying to tell...

    First order, non linear ode problem

    yeah, i don't understand what you mean when you say that its singular. Does that mean the particular solution does not exist?

    First order, non linear ode problem

    Ok.. I also get this as a solution y = -e^x/(ce^x-2) but this is also singular at y = 0.. i can't see the other obvious solution.

    First order, non linear ode problem

    Homework Statement Finding the general solution of y'= (2y^2)/e^x and the particular given that y(0) = 0 The Attempt at a Solution I separate variables etc. to get y = -1/(2c-2e^(-x)) where c is the constant. The problem then is obtaining the particular solution. If I substitute y and...

    How does Faraday's Law apply to a rotating coil in a magnetic field?

    Homework Statement A flat square coil of N turrns and area A is rotated at an angular velocity w in a uniform magnetic field of strength B. The rotation axis is perpendicular to the magnetic field direction. The coil is connected to a Galvonometer using suitable slip ring connectors and the...
