(x)= ln(x)/ x + x / e ^ xは1です。(x ^ 2-1)* exp(-x)も問題ありません。
x = 1:100:10000; y = log(x)./ x + x./(2.718).^x; plot(x、y) |
x = 1:10:200; y = 1+(x。^ 2-1)* exp(-x); plot(x、y) |
x2 = 1:500:500000; y2 = 1 + 0.001。* log10(x2); plot(x2、y2) |
x2 = 1:500:500000; y2 = 1 + 0.005。* log10(x2)。* log10(x2); plot(x2、y2) |
