※ 引述《bitchdog (PEaCE)》之銘言：
: lim t^3-t+2
: t→∞ ________________
: (2t-1)(t^2+t+1)
t^3 - t + 2
lim ---------------------
t→∞ (2t-1)(t^2 + t + 1)
(t^3)(1 - (1/(t^2)) + (2/(t^3)))
= lim -----------------------------------------
t→∞ (t^3)(2 - (1/t))(1 + (1/t) + (1/(t^2)))
1 - (1/(t^2)) + (2/(t^3))
= lim -----------------------------------
t→∞ (2 - (1/t))(1 + (1/t) + (1/(t^2))
1 - 0 + 0 1
= -------------------- = ---
(2 - 0)(1 + 0 + 0) 2
