In your symbolic evaluations you still have the degree symbol at the wrong position.
Furthermore the symbolic engine does not know anything about units. Its simply 'translates' the degree symbol ° to the unknow variable "deg".
Concerning a function depending on t you should have a second look at Stuarts answer.
He showed exactly that
Here with the resistance value 0,08.. ohm, which you had in your first sheet, and not with 0,8... ohm which you used later.
In your second sheet (the one which needs heavy cleaning) you defined a function e()
Like earlier with "sin" Prime assumes that you mean this function when you later use "e" and you would have to tell it by relabelling that you mean the built-in constant. Its more convenient not to use that function name.
You still have the degree symbol at the wrong position and you were missing the unit seconds on the o.oo5
ALT-0176 seems to be the same as ALT-248.
Both don't work in the unit placeholder
Only the degree from the unit menu does the job
This was implemented more user friendly in real Mathcad.
In Prime I often use ° when defining variables (because its easy with my keyboard, looks the way i want it and I am used to it) but I use "deg" when I display results (because the degree symbol here is to cumbersome). This unfortunately makes for quite inconsistent documents which I often can stand and it ends me re-editing the sheet 😞
You can also insert the degree symbol from Character Map - copy & paste.
I tried the (UK) Onscreen Keyboard (OSK) on my W11 Dell laptop, but Alt-0176 didn't do anything with the numeric keyboard enabled, and Fn-0176 entered the divide operator as soon as I pressed Fn-0. OTOH, there were some strange interactions between the OSK and physical keyboard, so that may have played a part.
The degree symbol position in the unit placeholder doesn't look right - too much space.
From the SI Brochure, 9th Edition:
5.4.3 Formatting the value of a quantity
The numerical value always precedes the unit and a space is always used to separate the unit from the number. Thus the value of the quantity is the product of the number and the unit. The space between the number and the unit is regarded as a multiplication sign (just as a space between units implies multiplication). The only exceptions to this rule are for the unit symbols for degree, minute and second for plane angle, °, ′ and ″, respectively, for which no space is left between the numerical value and the unit symbol.

This is not the only case for which Prime would not conform to ISO-80000-1.
Copying from the character table worked for me, but ALT-0176 from the numeric keypad did not (it inserted the ° symbol but at the same time a placeholder for the numeric value appeared, throwing the error. I could place a "1" there, but thats sure not an acceptable solution 😉
I wonder why copy and paste works OK but typing triggers an automatic input procedure.
When I re-edit worksheets to change "deg" to "°" I usually use the unit menu once and the do the rest with copy & paste. Nonetheless annoying work.
Not sure what you mean.
arccos, which is named acos in Mathcad, is a function with a unitless value (usually in the range from -1 to 1) as its argument and the RESULT of this function is an angle.
So of course its wrong to place the degree symbol after the function argument as you did in your first and third expression.
The second and fourth calculations wrong, too.
acos return an angle. If you add "deg" or "°" you multiply this angle by pi/180 and of course this leads to a wrong result.
You use "deg" only when you DEFINE or PROVIDE an angle in degree or when you DISPLAY and angle and want to see it in degree.
BTW, if there still is something unclear, I guess its time that you open an own thread for it.

Thank you Stuart for this clear example. Is there no way to set this up without having to take Transpose? Thank you.
No problem,
The data is in standard Mathcad column-vector format, so it's already set up correctly.
I prefer transposing vectors when displaying their contents. That way, they take up less vertical worksheet real estate, and the worksheets are generally more compact without losing clarity. IMO, tall vertical vector displays with lots of unused worksheet space make a worksheet harder to read. Plus, it just plain irritates me. 😀
