Hi dears
How to plot a level curve and the exact point of intersection between two different level curves.
I ploted the level curves and their point of intersection but that is not exact.

f(x,y)=m   (first level curve with m as a parameter)
g(x,y)=n   (second level curve with n as a parameter)
in both cases x and y varies from 0 to 1.
one way is
We will fix one level curve (say for m=0.5), and check the level curve intersection for n zero to 1. similarly we change m and again check the point of intersection b/W these level curves. 

I am interested in the tangential situation,I need those values of (x,y)where both curves are tangent to eachother.
