青賽今日在主場對陣騎士,這是東決系列賽的首場比賽。
談到青賽在這個系列賽取勝的機會,S.O'Neal在節目說:“青賽與巫師的上個系列賽是測
驗,這個系列賽則是考試,很難的考試。”
“雖然青賽是東區常規賽戰績最好的球隊,我向你們提出的問題是:他們真的相信他
們可以擊敗James麼?”O'Neal說道。

Final exercise(40%)
LeBron James question:
an approximation rule similar to the Trapezoid Rule is the Midpoint Rule.
This rule approximates the integral ∫(範圍從c到d) f(x) dx by (d-c) f
([d+c]/2). Prove that if the function f:[c,d]→R is continuous and its
restriction f:(c,d)→R has a second derivative,then for some point
ζ in (c,d).
∫(範圍從c到d) f(x) dx = (d-c) f [d+c]/2+1/24(d-c)^3*f''(ζ)
[hint: let m=(c+d)/2,letto=(d-c)/2 and define H(t)=[∫(範圍從(m-t)到(m+t)
f]-2tf(m)-(t/to)^3*∫(範圍從(m-to)到(m+to) f-2*t^3/to^2(f)m for -to<= t
<=to. apply the Generalized Rolle's thm. with n=1 to the function H:[-to,t
