Def of cosh
In mathematics, hyperbolic functions are analogues of the ordinary trigonometric functions, but defined using the hyperbola rather than the circle. Just as the points (cos t, sin t) form a circle with a unit radius, the points (cosh t, sinh t) form the right half of the unit hyperbola. Also, similarly to how the derivatives of sin(t) and cos(t) are cos(t) and –sin(t) respectively, the derivatives of sinh(t) and cos… WebPlease help me find cosh(-2) Transcribed Image Text: The hyperbolic cosine function, denoted by cosh, is defined by the equation. cosh(x) = -=-(ex + e-x) 2 (a) Without a calculator, find cosh(0). cosh(0) = 1 Using a calculator, find cosh(2) and cosh(-2), rounding the answers to two decimal places. cosh(2) = 3.7621 cosh(-2) = 1 Up
