(t^5+t^4+t^3+t^2+t+1)(t-1) 用直式计算
[T,Y]=ode45(@rigid,[0 1],[rand(15,1)]);plot(T,Y(:,1),'-',T,Y(:,2),'-.',T,Y(:,3),'.',T,Y(:,4),'-',T,Y(:,5),'-.',T,Y(:,6),'.',T,Y(:,7),'-',T,Y(:,8),'-.',T,Y(:,9),'.',T,Y(:,10),'-',T,Y(:,11),'-.',T,Y(:,12),'-.',T,Y(:,13),'.',T,Y(:,14),'-',T,Y(:,15),'.')
(2t+3)(2t-)-(4t+1)(t-9)
已知t-(2)/t=3,求4t/(t的平方-7t-2)
3t/4t-6,t+1/4t^2-9
4t-8/15t x 5t^2/6-3t
4t-8/15t x 5t^2/6-3t
(t+3t^2-3)-(-t+4t^2) 化简
(t+3t^2-3)-(-t+4t^2) 化简
初中数奥因式分解(1-7t-7t²-3t³)(1-2t-2t²-t³)-(t-1)6
Y(t)=3t^2-3t X(t)=4t^2-6t^3+5t 求Y(x)=?
化简t+1/t-(t+2)²-1/t²×t+1/t+3
3t^2-1=6t
利用行列式的性质证明| 1 1 1 || t t^2 t^3 |=t^4(t-1)^3(t+1) [这里的数字都是次方)| t^2 t^4 t^6 |
