## Returning an extra zero when using a vector

Hi,

I have a problem when using a defined vector in a function. As you can see below, the variable (i), goes from 1 to 3 with increments of 1.

When I use this variable in the function Dl(i) and Di(i) it returns one extra value in the answer, (0). (See where the arrow is pointing in the picture below)

This becomes a problem when I later on is going to use i.e. Di(i) in the equation shown below:

What I want to do is to remove this "extra" 0 for all functions of (i)

Anyone that can help me out?

Hi,

You have to set the origin to 1, write like this: ORIGIN: = 1. By default, in Mathcad, it is set to zero, therefore you find the first element of the vector equal to zero.
