PRO/E画弹簧x = 100 * cos ( 5*t *(2* 360 )*2)y = 100 * sin ( 5*t
PRO/E画弹簧x = 100 * cos ( 5*t *(2* 360 )*2)y = 100 * sin ( 5*t
t=0:pi/100:10*pi; x=2*(cos(t)+t*sin(t)); y=2*(sin(t)-t*cos(t
matlab中t=linspace(0,2*pi,100);x=[t;t]';y=[sin(t);cos(t)]';pl
设x=e'sin t,y=e'cos t,求dy/dx.
matlab 画图for t=0:0.5:5x=4*cos(3*t);y=4*sin(3*t);z=2*t;a=240*
Matlab u(x,t)=sin(5*pi*x)cos(5*pi*t)+2sin(7*pi*x)cos(7*pi*t)
用matlab 如何作出y与t的图?y=(sin(t)-sin(t0))^2 且 cos t+t*sin t-cos t
1.利用plot函数在区间[0,2π]同时绘制x=sin(t)和y=cos(t),z=sin(t)+cos(t)的图形.
利用plot函数在区间[0,2π]同时绘制x=sin(t)和y=cos(t),z=sin(t)+cos(t)的图形.要求
出处 h=2*pi/100;t=0:h:2*pi;r=0:0.05:1;x=r'*cos(t);y=r'*sin(t);
已知 x = e^t * cos t y = e^t *sin t 求当t= π/3时dy/dx的值
x=e^t (COS t) y=e^t Sin t
