假设是五阶展开。
syms x
taylor(x/(x+386)*0.9994^(x+386),x,'ExpansionPoint',662,'order',5)
最后结果是:
ans =
(331*exp(1048*log(4997/5000)))/524 + (x - 662)^2*((331*exp(1048*log(4997/5000))*log(4997/5000)^2)/1048 - (193*exp(1048*log(4997/5000)))/575511296 + (193*exp(1048*log(4997/5000))*log(4997/5000))/549152) + (x - 662)*((193*exp(1048*log(4997/5000)))/549152 + (331*exp(1048*log(4997/5000))*log(4997/5000))/524) + (x - 662)^4*((193*exp(1048*log(4997/5000))*log(4997/5000)^3)/3294912 - (193*exp(1048*log(4997/5000))*log(4997/5000)^2)/1151022592 - (193*exp(1048*log(4997/5000)))/632086358441984 + (331*exp(1048*log(4997/5000))*log(4997/5000)^4)/12576 + (193*exp(1048*log(4997/5000))*log(4997/5000))/603135838208) + (x - 662)^3*((193*exp(1048*log(4997/5000)))/603135838208 + (193*exp(1048*log(4997/5000))*log(4997/5000)^2)/1098304 + (331*exp(1048*log(4997/5000))*log(4997/5000)^3)/3144 - (193*exp(1048*log(4997/5000))*log(4997/5000))/575511296)
