If `f(x) = sgn(sin^2x-sinx-1)` has exactly four points of discontinuity for `x in (0, npi), n in N`, then

If f(x)=sgn(sin^(2)x-sin x-1) has exactly four points of discontinuity for x in(0,n pi),n in N, then

f(x)=sgn(x^(2)-ax+1) has maximum number of points of discontinuity then

f(x) = sgn(x^2 - ax + 1) has maximum number of points of discontinuity then

If f(x) = [2 + 5|n| sin x] , where n in I has exactly 9 points of non-derivability in (0, pi) , then possible values of n are (where [x] dentoes greatest integer function)

If f(x) = [2 + 5|n| sin x] , where n in I has exactly 9 points of non-derivability in (0, pi) , then possible values of n are (where [x] dentoes greatest integer function)

If f(x) = [2 + 5|n| sin x] , where n in I has exactly 9 points of non-derivability in (0, pi) , then possible values of n are (where [x] dentoes greatest integer function)

If f (x)= tan ^(-1) (sgn (n ^(2) -lamda x+1)) has exactly one point of discontinuity, then the value of lamda can be:

If f (x)= tan ^(-1) (sgn (n ^(2) -lamda x+1)) has exactly one point of discontinuity, then the value of lamda can be:

f(x)= underset(n to oo) (Lt) (sinx)^(2n) then set of points of discontinuity of f(x) is
