老师不改作业

我在MATLAB中输入了实验数据和一条拟合曲线,如何对比拟合曲线相对于真实数据的精确度?程序如clear;clc;%%%实验数据点x=[12,26,38,120,382,436,1266,11870,76120];y=[0.04419,0.03343,0.02762,0.01936,0.01484,0.01031,0.00 matlab中当参数取不同值时,让几条曲线出现在同一坐标轴中clc;clear all;syms c;syms c0;m=2*pi*1.46*(1/c-1/c0)+2*pi*1*10^(-4)/c;k=1*10^(-4)*pi/c;R=(sinh(((1*10^4*k)^2-(1*10^4*m)^2)^(1/2)))^2/((cosh(((1*10^4*k)^2-(1*10^4*m)^2)^(1/2))) I‘m very happy to find the my hometown is different from _____need to be.A that B what C how Dwhich 这题选B请解释为什么选B而不选别的（谢谢） VC++6.#include void main(){printf("abc");}一个简单输出,然后运行,瞬间显示了abc然后就自动关闭了,错误提示如下：Loaded 'ntdll.dll',no matching symbolic information found.Loaded 'C:\WINDOWS\system32\kernel32.dll',no matching you ( )thetraffic rules when you travel in a foreign country是选 A：don't have to know B:must know C:may not know 选哪个 when the thousands that travel to work every day are tucked away in their homes in the country.本句出自新概念第三册41课.请问本句话中的1.the thousands是什么意思?难道是指数以千计的人吗?2.这句话中的tucked是什么 _______ she took a walk in the park,she found a very strange thing.A.As B.while 为什么选A不选B 求__she took a walk in the park,she found very strange thing.
