`f(x)=(1-cosalphax)/(xsinx)`, for `x!=0, 1/2`, for `x=0` If f is continuous at x=0, then

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

Let f(x) = {:{((1-cosax)/(xsinx), x ne 0),(1/2, if x = 0):} If f is continuous at x=0, find a.

If f(x)={((1-coskx)/(xsinx) ,, x!=0),(1/2 ,, x=0):} is continuous at x=0, find k

For what values of k , f(x)={:{((1-coskx)/(xsinx)," if " x ne 0),(1/2," if " x =0):} is continuous at x = 0 ?

If f(x)={{:((1-cospx)/(xsinx)",",x ne0),((1)/(2)",",x=0):} is continuous at x=0 then p is equal to

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)={(1-cosk x)/(xsinx),x!=0 \ \ \ \ \ \ \ \ 1/2,x=0 is continuous at x=0, find k.

If f(x)={(1-cosx)/(xsinx),x!=0 and 1/2,x=0 then at x=0,f(x) is (a)continuous and differentiable (b)differentiable but not continuous (c)continuous but not differentiable (d)neither continuous nor differentiable

If f(x)={(1-cosx)/(xsinx),x!=0 and 1/2,x=0 then at x=0,f(x) is (a)continuous and differentiable (b)differentiable but not continuous (c)continuous but not differentiable (d)neither continuous nor differentiable

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