*Hyperbolic secant: <math>sech(x) = \frac{1}{cosh(x)} = \frac{2}{e^x + e^{-x}}</math>
*Hyperbolic secant: <math>sech(x) = \frac{1}{cosh(x)} = \frac{2}{e^x + e^{-x}}</math>
*Hyperbolic cotangent: <math>coth(x) = \frac{cosh(x)}{sinh(x)} = \frac{e^x + e^{-x}}{e^x - e^{-x}}</math>
*Hyperbolic cotangent: <math>coth(x) = \frac{cosh(x)}{sinh(x)} = \frac{e^x + e^{-x}}{e^x - e^{-x}}</math>
