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 = ?

For what value of k, the function f(x)={((tan2x)/(x)", if "x!=0),(k", if "x=0):} is continuous at x=0 ?

Find the value of k, if the function f given by : {:(f(x)=[tan((pi)/(4)+x)^(1/x)]",", "for"x ne0),(=k",", "for" x=0):} is continous at x=0.

If the function f(x) = {((cosx)^(1/x), ",", x != 0),(k, ",", x = 0):} is continuous at x = 0, then the value of k is

If the function f(x)={[(cos x)^((1)/(x)),x!=0k,x=0k,x=0]} is continuos at x=0 then the value of k]}

The function defined by f(x)={:{((1+tan^(2)sqrt(x))^((1)/(2x))", for " x!=0),(k", for " x=0):} , is continuous from right at point x=0 , then k=
