Hello, I have an equation which depends on the integral and differential of an unknown function f[x,y,z]. I would like to solve this equation analytically, however am happy with a numerical solution if that is necessary. The equation contains the unknown (f[x,y,z]) which I would like to solve for and has integrals of differentials like this : Integral [ d f[x,y,z] / dz , dx] Integral [ d f[x,y,z] / dx , dz] It is set up like this : (Integral [ d f[x,y,z] / dz , dx] )(knownTrigPoly1[y]) + (Integral [ d f[x,y,z] / dx , dz] )(knownTrigPoly2[y]) == 0 Any I would like to solve for f[x,y,z] (numerically if necessary). Can anyone let me know how to use DSolve or another function to solve this equation for f[x,y,z] ? thanks Matt -- http://www.flatmax.org Public Projects : http://sourceforge.net/search/?type_of_search=soft&words=mffm
