Hi,
I am very new to Mathematica, so need a bit of help!

I want to define a function (called say G) that is defined as

G = =E2=88=82/=E2=88=82x - ((=E2=88=82F/=E2=88=82x)/(=E2=88=82F/=E2=88=82=
y))*=E2=88=82/=E2=88=82y

Where F is some other function which will be defined.

So as you can see, G is a differenital operator. Want to define it so that I can just do G[ some function ] rather than repeatedly write out the whole thing.

Any help at all would be awesome!
