    Singular Points

    Can someone explain to me why there isn't a singular point in this ordinary differential equation?

    y'' + 4y' + (sin(x)/x)y = 0

    I have an idea as to why but I just want to be sure about it.

    Thanks,
    Simon

    I'll try and explain!
    If the singular point is 0, then because sin(0) = 0, the third term would disappear.

    This leaves y'' + 4y' = 0

    Therefore there are no singular points.
    Am I right or have I gone completely the wrong way?

    Thanks,
    Simon
