2nd order PDE charcteristics help please! :S

    hi all, sorry again for the thousands of stupid questions! :P but heres another one...

    ok i said for part (a) that the PDE is a hyperbolic type and so has two sets of real characteristics. and that the characteristics are http://img100.imageshack.us/img100/7770/picture14dj6.png [Broken]

    then for part (b) i used the coordinates:

    which leads to the equation:

    but then i am stuck... how can i get the 'general solution' from this, i think i am heading in the right direction, but i am not sure.

    any help would be greatly appreciated!

    thanks

    Sarah :)
