Abstract
In this paper, we study several degenerate trigonometric functions, which are degenerate versions of the ordinary trigonometric functions, and derive some identities among such functions by using elementary methods. Especially, we obtain multiple angle formulas for the degenerate cotangent and degenerate sine functions.
