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

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

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

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+sin x - cos x)/(1- sin x - cos x ) , x != 0 is continuous at x = 0 , then : f(0) =

IF the function f(x) defined by f(x) = x sin ""(1)/(x) for x ne 0 =K for x =0 is continuous at x=0 , then k=

Let f(x) = (1 - cos px)/(x sin x) , where x ne 0 and f(0) = (1)/(2) . If f is continuous at 0, then p is equal to :

Show that f(x) = x sin ((1)/(x)), x ne 0 , f(0) = 0 is continuous at x = 0
