Why The function APP failled to find an extremum in this case
Good morning dear "Primers",
Can you explain why the function App failed if i ask for an extremum of \(f(x)\)? \(f(x)=\frac{1}{9} \cdot (84\cdot x e^{3\cdot x}2 e^{3\cdot x}+2)\) Code: f(x):=1/9*(84*x*e^(3*x)2*e^(3*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

Hi,
in CAS environment, you have to type F1:=f instead, and it should work. primer
