Sin, Cos, Exp and some other functions are listable; with those you can use Through[{Sin, Cos, Exp}[{x, y}]] {{Sin[x], Sin[y]}, {Cos[x], Cos[y]}, {E^x, E^y}} Bobby "Xiaoji Liu" <chmlxj at hotmail.com> wrote in message news:<c1qm3a$39e$1 at smc.vnet.net>... > 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
