Hi,

I want to maximize

x1^2 + 4*x1*x2 + 3*x2^2  (eq.1)

under the constraint

x1^2 + x2^2 == 1 (eq. 2)

So far no problem, Maximize gives me 2 + sqrt(5)

But how can I display this visually?

For eq. 1 I can use Plot3D[], for eq. 2 ImplicitPlot[] but how to have
them in one picture?


Thanks in advance,


Uwe
