#nombre dérivé
# f'(a)=lim quand h tend vers 0 (f(a+h)-f(a))/h
# f'(a)= coefficient directeur de la tangente 

# équation de la droite tangente
# y=f'(a)(x-a)+f(a)


# si f est dérivable en a, alors la courbe représentative C de f admet, au point A d'abscisse a, une tangente non verticale de coefficient directeur f'(a) et d'équation :
#  y-f(a)=f'(a)(x-a)


# Dérivées des fonctions usuelles
# f(x)= k => f'(x)=0

# f(x)=x**n => f'(x)=nx**(n-1)

# f(x)= 1/x => f'(x) = -(1/x2)

# f(x)= sqare de x => f'(x)= 1/(2 sqare de x)





















# dérivées et opérations
# f'(x) = ag'(ax+b)
