The function sinh(x) is known as the hyperbolic sine function. It is defined mathematically as \sinh(x) = \frace^x - e^{-x}2, where e is the base of the natural logarithm. This function is used in various fields, including mathematics, physics, and engineering, to model certain types of growth and wave patterns. The graph of sinh(x) resembles that of the regular sine function but is not periodic. It increases rapidly for positive values of x and decreases for negative values, approaching zero as x approaches negative infinity. The function is odd, meaning that \sinh(-x) = -\sinh(x).
