she returned to the shop dressed in a fur coat dressed前为什么没有be动词为什么分词作状语省去Be 还有那些除了分词也要省略be的 这道题怎么用换元法求值域y=x+根号下（x-3）这道题怎么用换元法做啊 She has short,grey fur.(对has short,grey fur提问) ___ it ___? 淡淡的日子也飘香作文. “淡淡的日子也飘香”作文咋写? 当a=什么是,关于m,n的2元一次方程组m+n=6,m-n-9=3a的解满足2m=n 如何用matlab解下面的矩阵方程(A-B*R^-1*B'*P)'*P1+P1*G=-P*D*F其中：A=[0 1;-1 1];B=[0 1]';P=[3.3784 0.4142; 0.4142 2.6818];G=[0 1 0;0 0 1;-2 -2 -1];F=[1 0 0] 怎么用matlab的ode命令解下面的方程?上述方程我用matlab解后发现数值解和精确解差别较大,求帮助 Matlab方程求解问题.怎么解下面的方程!function F =Komulainen(x,F_aq,F1_aq,F_org,V,A,C,D,a,a1,alfa,beta,x_pls,x_el)% B = (beta*(35.15*x_pls+27.15*x(6)))% Ba = ((beta*(35.15*x_pls+27.15*x(6)))*a)% b = (x(6)-a*x_pls)F = [(F_aq/V)*(x(2)-x(1)) Matlab数值解下面的方程,具体见图：如有建设性思路、想法，或具体的程序一定加分我这样这样画图的：fun_fan.m文件中：function [ fun ] = fun_fan( d,N_eff )lambda_0=1.55e-6;k_0=2.*pi./lambda_0;epsilon_m=-127.8-3. 计算:(-1/2x的三次方)的二次方除以2/5x Tim was a very poor boy ,but now he is very rich .Every dog has its day .(question:“Every dog has its day”翻译成汉语意思是什么?） ___ was very rich,he never helped the poor.A Because B when C if D while 应该是B,C中的一个,是哪个?说错了 B ,D 中的一个. my sister keeps a dog as a p_______.what about you? ____Tom's mother is very poor,____ he loves her so much.A.Although;but B.But;although C./;butD.Althoughl;so .要选哪个?
