hi... I am new to this topic and frustrated.
I have a curve f(x,y)= -3y/(x2 +y2 + 1)
I was asked to draw a level curve of this and I'm not getting anywhere with it. If anyone has any pointers, or can help me with solving this question I would be gretfull. The only other thing this question asks is to describe it at the orgin or at (0,3) ( which is steeper).
thanks for any help.

Level curves are curves where the function is constant, and equals lets say to a number c.
So you get an equation
Rearranging this gives you
Now you just have to investigate different values of c.
