7.7 Hyperbolic Functions Math 6B Calculus II
Definition of Hyperbolic Functions • Hyperbolic Cosine (cosh) • Hyperbolic Sine (sinh) • Other Hyperbolic Functions
Hyperbolic Identities • sinh(-x) = -sinhx • cosh(-x) = coshx • cosh2x – sinh2x = 1 • 1 – tanh2x = sech2x • sinh(x+y) = sinhx coshy + coshx sinhy • cosh(x+y) = coshx coshy + sinhx sinhy
