Good morning dear "Primers",
Can you explain why the function App failed if i ask for an extremum of \(f(x)\)?
\(f(x)=\frac{1}{9} \cdot (84\cdot x e^{-3\cdot x}-2 e^{-3\cdot x}+2)\)
1) I create \(f(x)\) in CAS side. Have you notice the Latex command ? Did you know that ? !
CTRL+C CTRL+V to paste on these post !!! ;o) Thank's to M. PARISSE !
2) I choose F1(X)=f(X)
Here notice that the EVAL softKey do nothing !? Why ?
3)Plot and choose "EXTREMUM"
4) Can't find an extremum !!
[/code]
Thank's for reading.
Didier

Code:
f(x):=1/9*(84*x*e^(-3*x)-2*e^(-3*x)+2)
