underset(x to 0)"Lt" (e^(tan x)-1)/(sin x)=

Let f(x)=(e^(tan x)-e^(x)+ln(sec x+tan x)-x)/(tan x-x) be a continuous function at x=0. The value f(0) equals

Let f (x)= (e ^(tan x) -e ^(x) +ln (sec x+ tan x)-x)/(tan x-x) be a continous function at x=0. The value of f (0) equals:

lim_(x rarr0)(e^(x)-e^(x sec x))/(x+tan x) is equal to

e^(tan^(-1)x)log(tan x)
