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:

f(x)=(1-cos alpha x)/(x sin x), for x!=0,(1)/(2), for x=0 If f is continuous at x=0, then

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)}

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:

Find the values of k so that the function f is continuous at the indicated point f(x) = {((1- cos (kx))/(x^(2))",","if " x ne 0),((1)/(2)",","if " x= 0):} at x= 0

The value of k(k f(x)= {((1-cos kx)/(x(sin x)),x!=0 or (1)/(2),x=0} ,is continous at x=0 is :

Find the values (s) of k so that the following function is continuous at x=0 f(x ) = {{:( (1- cos kx )/( x sin x ) , " if " x ne o),( 1/2, I f x=0):}

if f(x)=(1-cos ax)/(x sin x)" for "x ne 0, f(0)=1//2 is continuous at x=0 then a=

If f(x)={[(cos x)^((1)/(sin x)),,x!=0],[K,,x=0]} is differentiable at x=0 Then K=
