Dear All

I have a this expression:

Ex= T1[x]+T2[y]+T3[z];

I want to integrate the first term with respect to x, the second w.r.t y and the third with respect to z and then sum them all. I want to use the map function (/@) or similar to do that for me automatically. Your help is really appreciated.

HMQ

Hi, Hussain,
Try this:

expr = T1[x] + T2[y] + T3[z];
Map[Integrate[#, #[[1]]] &, expr]

\[Integral]T1[x] \[DifferentialD]x + \[Integral]T2[
    y] \[DifferentialD]y + \[Integral]T3[z] \[DifferentialD]z

Have fun, Alexei
