Differentiate pi^3 (2 Viewers)

[Carrotsticks]

If you define "1" as a variable, then yes. But that's just a silly example. Pi, as said before, can represent a function or be a variable - so there are situations when it is "legal" to differentiate it - and not just a contrived example.

I have seen it used as a FUNCTION, but I have never seen it being used as a variable, as in

P(pi) = pi^2 - 1 and therefore solutions of P(pi) are pi = plus/minus 1.

Anyway, I am now closing this thread because OP has had their question answered and now this thread is now reducing to rabble.
