There are two ways to get a subscript:

If you want a subscript in a variable name, type "I.abc"

If you want to address an element of a vector, type "I[abc"

In your sheet you define i from 0 to 100 (an index variable) so don't type sx(i) {this defines a function}, type "sx[i", and sx becomes a vector of frequencies.

You need to read the help files about units--you're putting thrm in in some places and not others.

Hello Julia,

I see several culprits in your worksheet:

#1 you haven't defined the variable Iabc. And you're using it on both sides of your equation.

#2 you're using min and max as avariable. These are however, MathCad functions and shouldn't be overwritten.

#3 the same applies to your function s(i). s is a unit in MathCad.

Hope this helps

Raiko
