运算符号缺失、除 0 未处理,改成:
y=500+126*sin((pi/2).*(1+(x-1500)./1000))-5000./((1200-x)+eps*((1200-x)==0));
126和sin之间应该有*号吧,还有sin函数不能用中括号[ ],改成小括号试试。
y=500+126*sin((pi/2).*(1+(x-1500)./1000))-5000./((1200-x)+eps*((1200-x)==0));
x-y/x-x+y/y-(x+y)(x-y)/y² y/x=2
化简 x / y(x+y) - y / x(x+y) =
x(x+y)(x-y)-y(y+x)(y-x)=(x-y)( )填空
Y-X*0.09=2500 求问Y、X是多少.
matlab y=[ ]; x=0:0.1:2; y=[y,cos(x)]; plot(x,y) 其中y=[ ]和y=[y,cos(x)]; 啥意
解方程组 :x-y=0.1y 1.2x+11.2=1.15y更正:x-y=-0.1y
0.1y=2x,5x+y=5
0.1y =2x 5x+y=5
0.1x+0.3y=2.5 0.1x-0.1y=2.1,求x,y
x+x+y+y+y=21 ,x+x+y+y+y+y+y=27 ,x ,y=?
x+x+y+y+y=21 ,x+x+y+y+y+y+y=27 ,x ,y=?
y=x(x
800x+1200y=436650x+800y=240结果X,Y是多少?
方程组 x+y=18 { (x+0.12x)+(y+0.1y)=20
x+x+x+x+y+y+y=56
0.1x+0.3y = 0.15(x+y) 0.1x+0.3y+0.2×300 = 0.18×(x+y+300) x=?y=?
0.1x+0.3y = 0.15(x+y) 0.1x+0.3y+0.2×300 = 0.18×(x+y+300) x=?y=?
x+x+x+y+y=6.4 y+y+y+x+x=7.1 怎么算?
