XJ,

Outer[#1[#2] &, {Sin, Cos, Exp}, {x, y}]

{{Sin[x], Sin[y]}, {Cos[x], Cos[y]}, {E^x, E^y}}

Suppose I have a list of operators {Sin, Cos}, and a list of
variables {x,y},
I want to apply {Sin,Cos} on {x,y}, and the outcome to be
{{Sin[x],Sin[y]},{Cos[x],Cos[y]}}

I can achieve this by using Table function with a temporary counter i.

But is there any way to do this without using temporary counters?

Thanks,
XJ
