Little <i>Mathematica</i> Help for the EcQ?

I was wanting to visualize the EcQ function but don’t have the software skills to plot it out for all values of MET and SIT. If any kind heart out there would mind plotting it and sending me a picture of the graph to post here I would really appreciate it.

Basically, the function is:

Z = X ((X + Y) / 2)

Where both X and Y are real values from 0.0 to 1.0.

I’d like to see the 3D plot of Z for all values of X and Y.

Anyone interested in wasting their time on this? My e-mail is beckr@acu.edu
