(t+3t^2-3)-(-t+4t^2) 化简
(t+3t^2-3)-(-t+4t^2) 化简
(t+3t^2-3)-(-t+4t^2) 化简
(t+3t^2-3)-(-t+4t^2)
=t+3t^2-3+t-4t^2
=-t^2+2t-3.
-t^2+2t-3
都知道用电脑来敲,还不会这么简单的化简?
明显水帖,鉴定完毕
(t+3t^2-3)-(-t+4t^2) 化简
(t+3t^2-3)-(-t+4t^2) 化简
(2t+3)(2t-)-(4t+1)(t-9)
参考身高: 2T 3T 4T 5T 6T 8T是什么意思
(t^5+t^4+t^3+t^2+t+1)(t-1) 用直式计算
3t+t-2t=?
5t-3≤4t-1 7+2t>6+3t 3+t
5t-3≤4t-1 7+2t>6+3t 3+t
4t^-8t+5-3t^+6t-2 其中t=2/1
已知t-(2)/t=3,求4t/(t的平方-7t-2)
化简t+1/t-(t+2)²-1/t²×t+1/t+3
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~
4t^3-3t^2-2t+1=0 t等于多少
3t/4t-6,t+1/4t^2-9
4t-8/15t x 5t^2/6-3t
4t-8/15t x 5t^2/6-3t
已知f(t)=3t*t-2t-2/t+3/t*t,证明f(t)=f(1/t)
