The real sine function is periodic, but has well-defined intervals of invertibility. The complex sine function is also periodic, but its branches of inverse are "cross-connected." This image shows the graph of the complex sine function with the imaginary axis of the domain projected away. The real sine graph is the bright green curve running down the middle.
