    How to do this integral?

    dy/dx = (y^2 - 1)/x

    a) Give the general equation of the curves that satisfy this equation

    b) Show that the straight lines y=1 and y=-1 are also solutions.

    Thank you!!!!

    dy/(y^2-1)=xdx
    Proceed from there (integrate).

    b) what is the derivative of a straight line? is it equal to what the diff eq tells you about it?
