How many degrees are there in one complete sine wave cycle?

A complete sine wave cycle equals one full rotation of the angle, which is 360 degrees. As you move from 0° to 360°, the sine value goes through a full sequence: it starts at 0, climbs to 1 at 90°, returns to 0 at 180°, drops to -1 at 270°, and then comes back to 0 at 360°. After 360°, the pattern repeats, so the cycle length is 360 degrees. The other values are just fractions of the cycle—90° is a quarter, 180° is half, and 270° is three quarters—not a full cycle.
