Hyperbolic functions - Wikipedia
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.
How do you show (coshx + sinhx)^n = cosh (nx) - Socratic
2016年5月4日 · How do you show (cosh x + sinh x)n = cosh(nx) + sinh(nx) for any real number n? Use the definition coshx = ex + e−x 2 and sinhx = ex −e−x 2. Left Side: [ex +e−x 2 + ex − e−x …

calculus - Does rationality of $\cosh (nx)$ and $\cosh ( (n+1)x)
2016年4月28日 · You can easily generalize this to show that if n, m n, m are positive integers and cosh(nx) cosh (n x) and cosh((n + m)x) cosh ((n + m) x) are rational, then cosh(mx) cosh (m x) is rational
Hyperbolic Functions - Math is Fun
Hyperbolic Functions The two basic hyperbolic functions are "sinh" and "cosh": Hyperbolic Sine: sinh (x) = ex − e-x 2 (pronounced "shine") Hyperbolic Cosine: cosh (x) = ex + e-x 2 (pronounced "cosh") They use the natural exponential function ex And are not the same as sin (x) and cos (x), but a little bit similar: sinh vs sin cosh vs cos Catenary

Prove that (coshx+sinhx)^n=coshnx+sinhnx? | Socratic
2017年10月16日 · Prove that (cosh x + sinh x)n = cosh nx + sinh nx? Please see below. As coshx = ex + e−x 2 and sinhx = ex −e−x 2. and adding two coshx +sinhx = ex. and (coshx + sinhx)n = (ex)n = enx. also coshnx = enx + e−nx 2 and sinhnx = enx −e−nx 2. and coshnx + sinhnx = enx. Hence, (coshx + sinhx)n = coshnx + sinhnx. Proof by mathematical induction.
