Can someone tell me what is wrong with the following code?


Code:
ClrHome
Disp "Differentiation,","made easy."
Disp " ","Differentiate:"
Input Str1
Disp "w/ respect to:"
Input Str2
ClrHome
Disp "Derivative:"
Output(2,1,...Str1,Str2))
Pause
ClrHome
Can you tell us what it's suppose to do and what is wrong?


There are two types of people in the world: those who can extrapolate data from incomplete data
On the website I got it from, it said it was supposed to differentiate an expression with actual variables inside (not all numbers, have legit x terms or y terms, depending in what respect the differentiation is occurring). After getting the equation and in what respect, it should display a result.

I tried

Code:
X^2


In respect to


Code:
X


And the emulator and my TI-84 Plus ran into errors centering around


Code:
Output(2,1,...Str1,Str2))


If that helps at all trying to understand my confusion
The problem is that "..." before Str1 is not valid syntax; I'm not sure what the program's author was trying to indicate with that. Unfortunately, unless it's a much, much longer program with a lot of manual string parsing and manual differentiation rules, it's a hoax: the TI-83 Plus/TI-84 Plus family cannot natively do symbolic math including differentiation.
