Heat equation (cylindrical)

  1. Mar 14, 2010 #1
    I have tried to solve the cylindrical case of the heat equation and reached the second order differential equation for the function R(r):

    R'' + (1/r)*R' + (alfa/k)*R = 0

    (alfa, k are constants)

    I couldn't find material on the web for non-constant coefficients, does anyone know how to solve this?
