Abstract
In this chapter we introduce the p-trigonometric functions, for 1\(< p < \infty, \) and establish their fundamental properties. These functions generalise the familiar trigonometric functions, coincide with them when p = 2, and otherwise have important similarities to and differences from their classical counterparts. As will be shown later, they play an important part in both the theory of the p-Laplacian and that of the Hardy operator. Particular attention is paid to the basis properties of the analogues of the sine functions in the context of Lebesgue spaces.
