Dear all,
I am very new to this forum after a friend recommended it. I am preparing for my final graduation exam there is one question I can not solve
I was hoping perhaps someone could help me
a= a(x,y)
a*axy = ax*ay = xy (so a differentiated w.r.t. x and y)
a(x,0) = x
I need to find the solution of a using the method of characteristics. I only knew how to solve it using direct integration but this was not allowed
Thanks in advance
