紧线器2t 1. please don't tell anybody what I said don't worry .Iplease don't tell anybody what I said don't worry .I______.1.WON'T 2DON'T 3CAN'T 8WOULDN'T 1.4T 1.6T 1.这个T? 3t+t-2t=? t*exp(2t)对t求导 t/(t^2-t+1)的积分 T^T英语第2T (t+3t^2-3)-(-t+4t^2) 化简 （t+3t^2-3)-(-t+4t^2) 化简 计算 (t+2)(t²-t+1)+t-2 (2t+3)(2t-)-(4t+1)(t-9) t^2-t+2求导 因式分解：t^2-t-2 叶形线：x=2*t-t*t,y=2*t*t-t*t*t 图形怎么划? 微分方程 矩阵 x'(t)=x(t)+y(t)+2t y'(t)=x(t)+y(t)-2t 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 化简t+1/t-(t+2)²-1/t²×t+1/t+3
