0.1x+0.3y=2.5 0.1x-0.1y=2.1,求x,y
matlab y=[ ]; x=0:0.1:2; y=[y,cos(x)]; plot(x,y) 其中y=[ ]和y=[y,cos(x)]; 啥意
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+y-5)*(x+y-5)+(x-y+3)=0 x*x-y*y
已知:3x-5y=0,求x/y,x-y/y,x-y/x
y=-0.1x²+2.6x+43(0
高数最值y=x^x x属于(0.1,+无穷)
0.1y=2x,5x+y=5
0.1y =2x 5x+y=5
x=0:0.1:10; y=(x^2+9*x-128)/(x^2-2*x-22); plot(x,y)我编写MATLAB程序错在哪了
方程组 x+y=18 { (x+0.12x)+(y+0.1y)=20
MATLAB求助,程序为什么出不了图x=0:0.1:1 y=x.*exp(-x) plot(x,y),xlabel('x'),ylabel('y'),title('y=x*exp(-x)')
z=0.015x*x+y*x*0.05+(1-x-y)*2.5*(x+y) x>0.35.xy>0.70x+y
解方程组 :x-y=0.1y 1.2x+11.2=1.15y更正:x-y=-0.1y
解方程组{0.2x+0.3y=-0.1,0.5x+(y/3)=1
x+2/3-2y=-8 0.3x-0.1y=-1解方程
解方程{0.3x-0.7y=-0.4,1.3x-0.1y=1.2
