If `lim_(x rarr0)(ae^(x) -b)/x` , then find the values of a and b.

Consider the function f(x) = (x^2 - 4)/(x - 2) If lim_(x rarr a) (x^4 - a^4)/(x -a) = lim_(x rarr 0) (e^(4x) -1)/x , find all possible values of a.

lim_(x rarr 0)(1-x-e^(x))/(x^(2)) =

Evaluate lim_(x rarr 0) (tan x)/x

lim_(x rarr 0) (tan x- sin x)/x^3

Evaluate lim_(x rarr 0) (ax + b)/(cx + 1)

Evaluate lim_(x rarr 0) ((x+1)^5 - 1)/x

Evaluate lim_(x rarr 0)(ax+b)/(cx+1)
