(adsbygoogle = window.adsbygoogle || []).push({}); 1. Use the method of characteristics to solve: xu_{x}+yu_{y}=1

2. given condition of u(x,y)=1 when x^{2}+y^{2}=1

3. I know I need to transpose into the s-t domain. Using: du/ds=u_{x}dx/ds+u_{y}dy/ds=au_{x}+bu_{y}

so a=x & b=y...

please help

1. The problem statement, all variables and given/known data

2. Relevant equations

3. The attempt at a solution
