$$\sinh(x) \equiv \frac{e^x - e^{-x}}{2}$$ $$\cosh(x) \equiv \frac{e^x + e^{-x}}{2}$$ $$\tanh(x) \equiv \frac{\sinh(x)}{\cosh(x)} = \frac{e^{2x} - 1}{e^{2x} + 1 ...

For importance of the trigonometric integrals, we have in this paper finding a series of power, some of trigonometric functions that did not exist before in the first section. As shown in the Section ...

Excel has built-in functions for sine and cosine, the two core trigonometric functions, and for hyperbolic sine and hyperbolic cosine, their hyperbolic counterparts. It also has built-in functions for ...

Abstract: The restrictions imposed on the solutions of nonuniform transmission lines, the impedance of which can be described by various trigonometric and hyperbolic functions, have been relaxed here ...
