WebFind the Taylor series expansion of cosh (x): taylor (cosh (x), x) ans = x^4/24 + x^2/2 + 1 Rewrite the hyperbolic cosine function in terms of the exponential function: rewrite (cosh (x), 'exp') ans = exp (-x)/2 + exp (x)/2 Input Arguments collapse all X — Input Web5 Dec 2014 · 4 Answers. You may too use the method I used here for the expansion of tan : Integrate repetitively tanh ′ (x) = 1 − tanh(x)2 starting with tanh(x) ≈ x : Every integration gives another coefficient of tanh(x) = ∑ n ≥ 0an ( − 1)nx2n + 1 and we get simply : a0 = 1, an + 1 = 1 2n + 3 n ∑ k = 0ak an − k, forn > 0 i.e. the sequence ...

However how does one arrive at such an approximation? The usual way of calculating the Taylor expansion at x 0 = 12 does not result in such a nice expression for me. logarithms Web26 May 2024 · I have been trying to prove that the series expansion of sinh z around z = 1 is sinh z = sinh ( 1) + ( z − 1) cosh ( 1) + 1 2 ( z − 1) 2 sinh ( 1) + 1 6 ( z − 1) 3 cosh ( 1) + O ( ( z − 1) 4) I know that sinh z = ∑ n = 0 ∞ z 2 n + 1 ( 2 n + 1)! and I tried the transformation z → z − 1, but it didn't work.
