"sn(x)" is a mathematical function, which represents Jacobian elliptic sine function, also called Snake function. This is a special elliptic function to describe the properties of ellipses and related mathematical problems.

Jacobian elliptic sine function has periodicity, and its period and amplitude will change with the change of parameter k, so the image of Jacobian elliptic sine function may show different shapes and properties according to the specific parameter values.
