The sine function reaches its maximum at which coordinate?

Explanation:
Sine waves peak at 1, with maximum values occurring when the angle corresponds to pi/2 (and then every 2pi later). At x = pi/2, the sine is sin(pi/2) = 1, so the coordinate is (pi/2, 1). The other points give sine values of 0 or -1, not the maximum. Therefore, the coordinate where the sine function reaches its maximum is (pi/2, 1).
