Salut @OxyGenS !! 

 

Pour la E on te demande le DL d'ordre 1 en 1 

 

Tu as ta fonction f(x) =  x/\sqrt{}x

Tu as comme dérivée f'(x) = ( x\sqrt{}x) /2

 

DL= f(x) + f'(x) x h + o(h)  pour x=1 tu as → DL= f(1) + f'(1) x h + o(h) 

 

donc DL = 1 + 1/2 x h + o(h) 

 

Donc l'item est bien juste sauf que le h dans mon explication correspond au x dans ton QCM 

 

J'espère que c'est clair ! n'hésite pas à poser d'autres question !
