I have a problem with the step range

Dear all, I have a problem with the step range. I want to prevent the value 0.50 from appearing in the first term of the function f(x1), according to the first method. I tried using the `last` function, but I can't get it to fit the vector x1.

I have Mathcad version 11.

Any suggestions?

    In case you wanted to retain the range from zero for other reasons, there are a few other ways that can solve the problem.  For example, by using the built-in "lookup" function to exclude a value, or the user-defined function "rest"  that returns a vector without its first element.
