41/30
2t-2/3-t-1/2=2t+1/5
t=-7/6-1/5
t=-41/30
2t-2/3-t-1/2=2t+1/5
t=-7/6-1/5
t=-41/30
4t^-8t+5-3t^+6t-2 其中t=2/1
3t^2-1=6t
已知f(t)=3t*t-2t-2/t+3/t*t,证明f(t)=f(1/t)
5t-3≤4t-1 7+2t>6+3t 3+t
5t-3≤4t-1 7+2t>6+3t 3+t
2t^3-6t^2+6t=1 求t要有计算过程
(2t+3)(2t-)-(4t+1)(t-9)
[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),'.')
化简t+1/t-(t+2)²-1/t²×t+1/t+3
(t^5+t^4+t^3+t^2+t+1)(t-1) 用直式计算
3t^2+3t-1-t^3=0,
79.788456t - 1250t^2 - 8311.297508t^3 = 1
当t=1时,代数式t^3-2t[2t^2-3t(2t+2)]的值
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 |
画出下列信号的波形1)f(t)=tu(t); 2)f(t)=t[u(t)-u(t-2)]; 3)f(t)=(t-1)u(t-1); 4)f(t)=sint/t画出图形~
3t+t-2t=?
t/(t^2-t+1)的积分
5t(2t-3)=(t+2)(t-2)-1 公式法
