So, I've been able to work through all the values so far but seems like I have a problem with the summation notation since the THD of alpha does not converge to a solution:
Prime knows and index and a subscript.
Index
If you have a vector V (=an array of values), and you want to point to a specific element in that vector you use an index. You type V[1 to get:
Which means/points to, the value of V at index 1. If V is defined as:
Then
Because by default index counting starts at 0. You can change the starting value by setting the value of ORIGIN (all capitals, yes). You can find its setting by evaluating it:
Subscript
Subscripts are part of a variable, You can subscript characters of a variable by pressing [Ctrl-_] (That is depressing the [Ctrl] key and tapping the [-] key, that's the key above which the underscore symbol '_' is shown.). Here's an example:
I first typed VariableAndBackUp, then moved the cursor to just after the e, en then put a [Ctrl-_] and typed WithAsubscript to get this variable name. Note that [Ctrl-_] gets you in the subscript, but there's no way to get you back up (as far as I know).
It's important to understand the difference between an index and a subscript:
If you have a variable with an index, and you put the cursor on it, Prime will show a grey [ symbol.
Success!
