I'm not too sure whether I should have posted this in the Physics section or in the maths Please move this topic if its in the wrong place!

this probably seems like a silly question but is it possible to plot x*y + c on a graph where c = a constant? I'm working on a question on fluid mechanics where I have to find the streamfunction and plot the stream lines. However I'm in doubt whether i have done the question correctly in the first place.

Please help!

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

For the 2D velocity fieldu= xi- yjfind the streamfunction 'psi' (apologises, I'm not too familiar with Latex)

2. Relevant equations

given above

3. The attempt at a solution

After partially differentiating and using formulas from my notes, i got psi = x*y + c
