Hello I have two functions of surfaces F1=\!\(\(-7.516\)*\ Exp[\(-3.076\)*\((r - 1.184)\)]*\((1 - 8.28*10\^\(-5\)*\((180\ - \ f)\)\^2)\)*0.7\^0.5 + 3.758*Exp[\(-6.152\)*\((r - 1.184)\)] + 3.92\) and F2=\!\(\(-0.958\)*\ Exp[\(-4.993\)*\((r - 1.375)\)]*\((1 - \ 1.07*10\^\(-3\)*\((133\ - \ f)\)\^2)\)*1\^0.5 + 0.479* Exp[\(-9.986\)*\((r - 1.375)\)] + 0.479\) variables are r and f I want to find a plot which describes crossing of these functions. I tried Solve command but without any success I also tried a simpler example Fa=Exp[-(x^2 + y^2)] and Fb=0.5 and when I used Solve[Fa == Fb, {y}] I received y1 and y2 - two parts of wanted function How to obtain one function (circle) from the above Fa nad Fb? Please Help Pawel
