Expansion of sinhx
Web3. Defining f(x) = sinhx We shall now look at the hyperbolic function sinhx. In speech, this function is pronounced as ‘shine’, or sometimes as ‘sinch’. The function is defined by the formula sinhx = ex −e−x 2. Again, we can use our knowledge of the graphs of ex and e−x to sketch the graph of sinhx. First, WebDec 30, 2024 · The simplest way t get it is to write sech x 1 cosh x and to use the MacLaurin expansion of cosh x at order 4 : cosh x 1 + x 2 2 + x 4 24 + o ( x 4) You obtain the expansion of its reciprocal dividing 1 by the MacLaurin expansion of cosh x along , up to order 4, truncating every term at order 4 in this process: 1 − x 2 2 − x 4 24 − 1 − ...

WebSo you can substitute somewhat conveniently: ln(cos(x)) = ln(1 + ∞ ∑ n = 1( − 1)nx2n (2n)!) = ∞ ∑ m = 1( − 1)m + 1( ∑∞n = 1 ( − 1)nx2n ( 2n)!)m m. This looks horrible, but it isn't actually so bad if you use the binomial theorem in the right way. With m = 1 you get terms of degree 2, 4, 6, …; with m = 2 you get terms of ...
