If `f(x)=log(sec^(2)x)^(cot^2x)` for `xne0` and `k` for ` x=0` is continuous at `x=0`, then `k` is

If {:(f(x),=(log)(sec^2x)^(cot^2x),",","for"x != 0),(,=k, ",","for"x = 0):} is continuous at x = 0 then k is

If {:(f(x),=(sec^2x)^(cot^2x),",",x != 0),(,=k, ",",x = 0):} is continuous at x = 0 , then k is equal to

If {:(f(x),=(sec^2x)^(cot^2x),",",x != 0),(,=k, ",",x = 0):} is continuous at x = 0 , then k is equal to

For what value of k , the function defined by f(x) =(log (1+2x) sin x^(0))/(x^(2)) for x ne 0 =K for x=0 is continuous at x=0 ?

f(x)={{:(sinx/x", " xne0),(k-1", " x=0):} is continuous at x = 0, then 'k' is :

If the function {:(f(x),=[log((pi)/4+x)]^(1/x),",","for"x != 0),(,=k, ",","for"x = 0):} is continuous at x = 0, then k = ?

if the function f(x) defined by f(x)= (log(1+a x)-"log"(1-b x))/x , if x!=0 and k if x=0 is continuous at x=0 , find k.
