Apr 12, 2024 · The basic sine and cosine functions have a period of 2π. The function sinx is odd, so its graph is symmetric about the origin. The function cosx is even, so its graph is symmetric about the y -axis. The graph of a sinusoidal function has the same general shape as a sine or cosine function.
