Hello to everybody
How can I modify the code below (after Epilog) in order to add after
"b^2-4ac=" its computed value and have everyhing framed?
a=0.5;b=1;c=6;d=2;e=3;f=-30;
ContourPlot[{a x^2 +b x*y + c y^2 + d x + e y - 30 == 0 }, {x, -12,
10}, {y, -8, 8
}, ContourStyle-> {Red, Thick}, Axes -> True, AxesLabel-> {x,y} ,
Frame-> False,ImageSize-> {550,400}, Epilog->{Text[Style["b^2 -
4ac=",FontSize-> 20],{5,5}]}]
I haven't found in the Mathematica 8 Documentation center a similar example.
Thanks
