Abstract

This chapter completes our study of the basic fuzzy functions. In Section 8.4 we had the fuzzy functions from linear to logarithmic The next section introduces the fuzzy trigonometric functions, their inverses (see Section 8.5) and their derivatives (see Section 8.6). We also see to what extent the basic crisp trigonometric identities will hold for the fuzzy trigonometric functions. Finally, the fuzzy hyperbolic trigonometric functions are in the third section.
