Review Questions

• Explain the relationship between the hyperbolic functions and the exponential function, and how this relationship is reflected in the derivatives of the hyperbolic functions.
  • The hyperbolic functions, such as sinh(x) and cosh(x), are defined in terms of the exponential function, $e^x$, and its inverse, $e^{-x}$. Specifically, $ ext{sinh}(x) = rac{e^x - e^{-x}}{2}$ and $ ext{cosh}(x) = rac{e^x + e^{-x}}{2}$. This connection to the exponential function is reflected in the derivatives of the hyperbolic functions, which are also hyperbolic functions. For example, the derivative of $ ext{sinh}(x)$ is $ ext{cosh}(x)$, and the derivative of $ ext{cosh}(x)$ is $ ext{sinh}(x)$. This allows for efficient computation and analysis of rates of change in various applications involving the hyperbolic functions.
