Hi,

I'll have to found the equation of equilibrium in terms of displacement for shell with double curvature. Well, I have 3 equations and 3 other equations that I must put in the others 3. Manually it's a suicide, ho can i do it with Maple and at the end semplify the differential equations? My problem is to say at Maple the dipendence of some function from other variable!

Thanks a lot!
