" (vii) "e^(tan x)

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:

" (d) "int e^(tan x)sec^(2)xdx

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

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

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

Period of f(x)=sin^(-1)(sin x)+e^(tan x) is

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

1. int e^(-tan x)sec^2xdx

int_((-pi)/(4))^((pi)/(4)) (dx)/(1+e^(tan x))

solve int e^(tan x)sec^(2)xdx
