Hallo Anonymous,

$${f}{\left({\mathtt{x}}\right)} = {\frac{{\mathtt{3}}}{{{\mathtt{x}}}^{{\mathtt{2}}}}}$$       =>    $${f}{\left({\mathtt{x}}\right)} = {\mathtt{3}}{\mathtt{\,\times\,}}{{\mathtt{x}}}^{-{\mathtt{2}}}$$

 

f'(x) = $${\mathtt{3}}{\mathtt{\,\times\,}}\left(-{\mathtt{2}}\right){\mathtt{\,\times\,}}{{\mathtt{x}}}^{-{\mathtt{3}}}$$  =   $${\mathtt{\,-\,}}{\frac{{\mathtt{6}}}{{{\mathtt{x}}}^{{\mathtt{3}}}}}$$

 

Gruß radix !     ( und eine gute Nacht ! )
