d2y or dx2

  1. S

    solving (x+a)^2 d2y/dx2 -4(x+a) dy/dx + 6y = x

    Hi, my question is that can we find the particular integral of this kind of equation by variation of parameters? If yes, then what mistake did I make in my solution in the provided link? If this is not the method to adopt, what other method can we use?

    Please Help with d2y/dx2

    What is d2y/dx2 of y^4=x^5? I have tried everything, every calculator or website gives me a different answer. Please help, thanks.

    d^2y/dx^2

    How do I find d^2y/dx^2at the point (1, 4)? x^2 - y^2 = -15 If I knew how to find the 2nd derivative, I could figure out the rest...

    d^2y/dx^2 of a parametric equation

    I can't seem to figure it this one out... x=1-5cos(t) y=7+cos^5(t) they want to find d^2y/dx^2 as a function of (t)
