Abstract
We establish some recurrence relations for the successive derivates atx=0 of some trigonometric and hyperbolic functions. We also construct an arithmetical triangle which gives immediately, by recurrence, the derivatives of the desidered order, of the functions sec, tan, cosec, cot, sech and tanh.
