x=0:0.001:8 y=x.^2/sqrt((1-x.^2).^2+(0.4*x).^2); plot(x,y)画出
mathematica,可以画出 Plot[n,{x,0,2Pi}] 但是 画不出 y=D[n,x] Plot[y,x]
(1/2)x=0:0.01:1;y=2.5x/(1.5x+1);plot(x,y)在matlab中画出其图象时,为什么出
matlab中 >> x=-1:0.001:1; >> y=log((1+sqrt(1-x.^2))/x)+sqrt(1
x=0:0.01:100; y=2^x.; plot(x,y) 为什么出错?
x=-20:0.01:20; y=x.*x+2; plot(x,y( :,20))后面的(x,y( :,
matlab画图x = 0:0.01:10; y =sin(2*x)*cos(100*x)/(2*x); plot(x,
x=0:0.001:2; y=humps(x); plot(x,y); 如何求其最大值,需要matlab的程序?
matlab中写入代码:x=0:0.1:1; y=(1+2*x)^(1/2) ; plot(x,y)
lim (sqrt(x+2)-sqrt(x))/(sqrt(x+1)-sqrt(x)) (X趋近于正无穷)
证明不等式:x/(sqrt(y))+y/(sqrt(x))>=sqrt(x)+sqrt(y)
matlab程序:[X,Y] = meshgrid(-8:.5:8); R = sqrt(X.^2 + Y.^2) +
lingo中min=sqrt(x^2+(y-a)^2)+sqrt((x-b)^2+(y-c)^2)+y;为啥不对
