    And is it a mistake that it says dx/dy instead of dy/dx ?

    Hmm I'm pretty sure this is not linear is either x or y. Does the book say it is? :o

    It's not from the book, straight from my prof. :/

    the question is... explain why this ODE is linear and then solve it..

    OH yes maybe it is a typo! Because it appears to be linear if that derivative term is dy/dx.

    Otherwise I don't see a way to make it linear in x or y. Man I just took Diff EQ last semester, you would think I had remembered some of it :P grr

    @zepdrix, if it was dy/dx... What makes it learn? Just that it is in the right form?

    Ummmm because we can get it into the form,\[\large y'+p(x)y=q(x)\] See how this form has no powers on y, and no weird functions of y,`like cos y`? If I remember correctly that's what makes it linear, if we can put it into that form.
