Formulas and Identities of Hyperbolic Functions Pacharapokin Chanapat Shinshu University Nagano, Japan Hiroshi Yamazaki Shinshu University Nagano, Japan Summary. In this article, we proved formulas of hyperbolic sine, hyper bolic cosine and hyperbolic tangent, and their identities. MML identiﬁer: SIN COS8, version: This single-volume compilation of three books centers on Hyperbolic Functions, an introduction to the relationship between the hyperbolic sine, cosine, and tangent, and the geometric properties of the hyperbola. Hyperbolic functions, inverse hyperbolic functions, and their derivatives identity for sine and cosine. Hyperbolic functions also satisfy many other algebraic iden-tities that are reminiscent of those that hold for trigonometric functions, as you will see in Exercises 88– without the help of hyperbolic functions. The first systematic consideration of hyperbolic functions was done by the Swiss mathematician Johann Heinrich Lambert (). Definitions The hyperbolic cosine function, written cosh x, is defined for all real values of x by the relation cosh x = 1 2 ()ex +e−x Similarly the hyperbolic sine. Hyperbolic Trigonometric Identities. The hyperbolic sine and cosine are given by the following: coshθ=eθ+e−θ 2,sinhθ=eθ−e−θ 2. The other hyperbolic trigonometric functions are defined in a similar way as the regular trigonometric functions: tanhθ cothθ sech θ csch θ=sinhθ coshθ=eθ−e−θ eθ+e−θ =1 tanhθ=eθ+e−θ eθ−e−θ =1 coshθ =1 sinhθ.the hyperbolic functions, which also provides practice in using differentiation multiplication and addition of such numbers, and the use of Euler's formula ei0θ. Check. a = bcosC + ccosB, or use Newton's formula or law of tangents. Note. In this case there may be two solutions, for C may have two values: C1 < 90° and. Hyperbolic Trigonometric Functions. Definition using unit If we use all values of , the points (cosh ,sinh ) form the Double angle identities sin(2 ). be able to find derivatives and integrals of hyperbolic functions;. • be able to find inverse hyperbolic functions and use them in calculus applications;. • recognise. whereas trigonometric functions can be related to the geometry of a circle (and are sometimes corresponding identity obeyed by hyperbolic functions though, in some cases, the Use Osborn's Rule to write down hyperbolic identities for. (a ).
