I wonder whether it is possible to use the Implicit Plot command in conjunction with the FindRoot command for the following type of problem: F(x,y1,y2,y3,y4,y5)==0 is an implicit function determining the endogenous variable x given the parameters y1,y2,y3,y4,y5 (and possible others) that is, even though there is no explicit (closed form) solution x(y1,y2,y3,y4,y5) there is an implicit relationship. My problem is to produce an implicit plot between the parameters y1 and y2 (where numerical values of the other parameters y3,y4,y5 are specified)given the implicit solution x(y1,y2,y3,y4,y5), i.e. an implicit plot between y1 and y2 such that F(x(y1,y2,y3,y4,y5),y1,y2,y3,y4,y5)==0. The question is whether (or rather, how) the ImplicitPlot-command and the FindRoot-command can be used in conjunction to solve this type of problem. thanks niko
