test for falling with the bounds of intersecting 2 dimensional cur
I am trying to validate if specific (x,y) coordinates fall within the area
bounded by intersecting curves with equations "y=f(x)", and am looking for help to set this up. I have tried the normal logic of IF, AND, OR but have not been successful at all. Has anyone ever tried this in Excel, or am I the first one to venture into this area? -- Mukesh |

I sorry not to have mentioned that I am working with EXCEL 200 and EXCEL 2003.

How many intersecting curves define your area? If it is defined by 2
curves, such as where f1(x) is =x and f2(x) is =x^2-5*x, then your formula for (xvalue,yvalue) being within the area would be =(yvalue<f1(xvalue))<(yvalue<f2(xvalue)) -- David Biddulph "Mukesh" wrote in message ...

I have four functions of the type "y=f(x)". Actually the fourth one is the
CIE 1931 locus of the human eye response to colors, and is a very complex function. The others are more like "y = mx+c". Since the complex function is represented by an instrument's data input, the data will always be bounded on that side. I am currently more concerned with the first 3 equations of the first order, and would just like to ensure that my data points are within their bounds. -- Mukesh "David Biddulph" wrote: How many intersecting curves define your area?
