8.3: HYPERBOLIC FUNCTIONS Circular functions (cos, sin) Let t be a parameter measured in radians; you will study parametrizations in Chapter 13 in Calc II. ( x = cos t . yt = sin . Remember, cos sin 22 1 tt += .) As t varies, we sweep out the unit circle given by xy 1 . The area A t = 2 02 ££ () t p . Why?: A t = Ê Ë Á ˆ ¯ ˜ () = radians corresponds to what fraction of a full revolution? area of a unit circle 123 { Hyperbolic functions (cosh, sinh) Let t be a parameter measured in “hyperbolic radians.” Consider the “unit hyperbola” given by
