2016年2月17日 · If we wanted to find, for example, the taylor series of #cosh(x)# around #x=0# then we set #x_0=0# and use the above definition. It is best to lay out two columns, one with the derivative and the other evaluating the value of #f^n(x_0)# at the point we wish to expand around. #f(x) = cosh(x)# #f(0) =1# #f'(x) = sinh(x)# #f'(0)=0# #f''(x) = cosh ...

2014年12月19日 · The definition of cosh(x) is (e^x + e^-x)/2, so let's take the derivative of that: d/dx ((e^x + e^-x)/2) We can bring 1/2 upfront. 1/2(d/dxe^x + d/dxe^-x) For the first part, we can just use the fact that the derivative of e^x = e^x: 1/2(e^x + d/dxe^-x) For the second part, we can use the same definition, but we also have to use the chain rule. For this, we need the derivative of …
