0/0 is indeterminate form and you must use l'hopital's rule: f (x) = [1 - (cos (x))^2]/ (2x^2). so the limit is obviously 0/0 which is indeterminate form. h' (x) = 4x. So the limit as x->0 of f (x) = lim x->0 g' (x)/h' (x) = 0/0: still indeterminate. Let's use l'hopital's rule again.

This is an indeterminate type so use l'Hopital's Rule  L'Hospital's Rule states that the limit of a quotient of functions is equal to the limit of the quotient of their derivatives. limx  Evaluate limit as x approaches 0 of (e^x-e^(-x)-2x)/(x-sin(x)). limx→0ex−e−x−2 xx−sin(x) lim x → 0 ⁡ e x - e - x - 2 x x - sin ( x ). Evaluate the limit of the  Apr 14, 2017 Taylor series of cos2x−cosx−excosx+ex is x32+x42+O(x5). Therefore, limx→0 cos2x−cosx−excosx+ex−x32xn=limx→0x42+O(x5)xn. If n=3, the limit goes to  Tricky computation: sin(x)+cos(x)−exlog(1+x2)=(sin(x)−x)+(cos(x)−1)−(ex−1 −x)log(1+x2)=(sin(x)−x)x2+(cos(x)−1)x2−(ex−1−x)x2log(1+x2)x2.
