May 5,2008 SelisÖnel© 3 Nonlinear Functions of Several Variables System with two nonlinear functions and two variables z=f(x 1 ,x 2 ) and z=g(x 1 ,x 2 ) Problem is more difficult to solve for more variables f(x 1 ,x 2 ,x 3 ,…,x n ) To find a zero of the system, find the intersection of the curves: f(x 1 ,x 2 )=0 and g(x 1 ,x 2 )=0 Use all the information about the problem to find the region where the curves may intersect SO…
