vector function integration problem

Problem of vector function integration.PNG

Best answer by Werner_E

Its a long standing wish that Mathcad should be able to deal with vectors of functions but as it seems in vain.

Here is another workaround which does not require you to redefine your integral function. Still unneccessarily awkward.

The problem is: From Mathcads point of view, f is NOT a vector, but the result f(t) is a vector.

So you cannot write f[1(2)= (you get a multiplication sign after f[1), but you can write f(2)[1=

Here is a variant of the above which only can be evaluated symbolically

or that way

Guess I'm lacking some knowledge...

Ah, found it: f2(t) *g2(t)=3*t^2+2*t^3.
