समीकरण sin(πx3√2) = x2 - 4x + 6 के वास्तविक हलों की संख्या है:

If 3 sin2(t) - 12 sin(t) - 3 = p, then the sum of all integral values of 'p' such that the equation has at least one real root is:

Let x ∈ [−π, π] and S = {x : sin x(sin x + cos x) = a, a ∈ &bold;Z&bold;}. Then the number of elements in set S is equal to:
