Right ok I’m stuck on trying to solve this using method of characteristics. I have tried using $au_x + bu_y = c$ but because it’s an $yx^2$ I can’t go further.



$u_x + (yx^2 +x)u_y = 1$

    It's an example question I don't understand. I got $a=1 b=yx^2 + x and c=1$ when I assign to the general case I don't know where I would go next

    The solution can be expressed with elementary functions, but one of the two equations for the characteristics is complicated (The other being $u=x+c$). Too complicated. What is the example for?

    I'm a student and it's just an example that was asked to work on in own time.. I know how to go about it if it didn't include $x^2$ looking for help starting it off then I can continue to work through

    You have an answer, the two equations for the characteristics, in my previous comment. Only need one step more for the general solution.
