Question

Can the function name be defined as kind of variable?

I am coding a formula in the form of a summation over a series of function V, something like:

Here, the subscript n is a variable which means the function V varies as subscript n increases. Vn is known before the computation.

I have no idea how to implement this in Mathcad, if someone can give me any suggestion, that will be really appreciated.

Unfortunately Mathcad's support for vectors of functions is very limited.

You could do it as shown below, but as your sums runs up to infinity - we obviously cannot define an infinite number of functions manually.

Therefore I guess all of your functions have the same structure and are in some way dependend on n. So you could make n a third (or first 😉 parameter of one single function V.
