u'+v'=u+v
u'un = un+1/n+1
u'/u = ln(u)
u'/rac u = 2 rac u
u'eu = eu

COSINUS SINUS 
periodique si -> f(x+T)=f(x)
cos(x+2pi)=cos(x)
sin(x+2pi)=sin(x)
paire si f(-x)=f(x)
fonc cos est paire-> 
  cos(-x)=cos(x)
imapire si = f(x)=f(-x)
sin impaire -> sin(x)=sin(-x)
derivable -> cos'(x)=-sin(x)
sin'(x)=cos(x)

f'(x)=-u'(x)sin(u(x))
et g'(x)=u'(x)cos(u(x))
ex = f(x)=cos(3x+1)
u=3x+1 u'= 3
donc f'(x)=3sin(3x+1)
