The minimum number of points required to mark all maximum, minimum, and zeros in a period of a sinusoid would be 5 points.
What is the period of sine function?
Trigonometric functions are periodic.
They repeat their values after some specific constant input interval (constant depends on the trigonometric function chosen).
One period of a sinusoid with no constant component has
1 maximum,
1 minimum,
1 zero crossing,
2 zero end-points.
therefore, the total points required will be 5 points.
