Came accross interesting problem in some GATE computer science paper. Consider the function f(x) = sin (x) in the interval x ∈ [π/4, 7π/4]. The number and location(s) of the local minima of this function are (A) One, at π/2 (B) One, at 3π/2 (C) Two, at π/2 and 3π/2 (D) Two, at π/4 and … Continue reading Function minima and maxima recap.
