WebIn this section, we look at differentiation and integration formulas for the hyperbolic functions and their inverses. Derivatives and Integrals of the Hyperbolic Functions Recall that the hyperbolic sine and hyperbolic cosine are defined as sinhx = ex − e−x 2 andcoshx = ex + e−x 2. WebSep 7, 2007 · The fundamental solutions to the differential equation y"- y= 0 are cosh(x) and sinh(x). If y is a solution to y"- y= 0 satisfying y(0)= A, y'(0)= B, then y(x)= A cosh(x)+ B … horns in the sky phenomenon
