Final answer:
The coordinates of the vertex A of the curve with the equation y = sin(x) are (0, 0).
Step-by-step explanation:
The vertex of a sine function of the form y = A sin(Bx + C) + D is given by the point (C, D).
In this case, the vertex of the function y = sin(x) is located at (0, 0).
Therefore, the coordinates of the vertex A of the curve with the equation y = sin(x) are (0, 0).
