what do you get by trying to find

lim -(cos(x)-1)/x
x-- 0

i have tried by doing the supervision of the function (f(x) superior or equal to and inferior and equal to)
but i cant get a good lim

You can try firstly turning the cosx to sin(x/2) and then use the equivalent infinitesimal between sinx and x
