The value of `k(k<0)` for which the function `f` defined as
f(x)= `{((1-cos kx)/(x(sin x)),x!=0 or (1)/(2),x=0}`,is continous at x=0 is :

If the function f(x) = {((1-cos kx)/(x sin x),x ne 0),((1)/(2), x = 0):} is continuous at x = 0, then the value (s) of k are:

The value of k (k lt 0) for which the function ? defined as f(x) ={((1-cos kx)/(x sin x),","x ne 0),((1)/(2),","x=0):} is continuous at ? = 0 is:

If f(x)={((1-cos kx)/(x sin x),x!=0),((1)/(2),x=0)} is continuous at x=0, find k,((1)/(2),x=0)}

The value of k for which f(x)= {((1-cos 2x )/(x^2 )", " x ne 0 ),(k ", "x=0):} continuous at x=0, is :

If f(0) = 2 , and f(x) = (1-cos kx)/(x.sin x) , x != 0 , is continuous at x = 0 , then : k =

If f(x)={((1-cos x)/(x)",",x ne 0),(k",",x=0):} is continuous at x = 0, then the value of k is

If the function f(x) {((1 - cos 4x)/(8x^(2))",",x !=0),(" k,",x = 0):} is continuous at x = 0 then k = ?

The value of k which makes f(x)={:{(sin(1/x)", for " x!=0),(k", for " x=0):} continuous at x=0 is
