這只是一篇課文拿來賺P幣跟練英打的，因為我輸光光了（T口T）＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝以下是課文內容，不想看可以<-離開＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝ the linearization of a function f(x) about x=a , namely,the linear function describes the behaviour of f near a better than any other polynomial of degree 1 because both P1 and f have the same value and the same derivative at a: (we are now using the symbol P1 instead of L to stress the fact the linearization is a polynomial of degree at most 1.) We can obtain even better approximation to f(x) by using quadratic or heiger- degree polynomial and matching more derivatives at x=a.For example,if f is twice differentiable near a,then the polynomial satisfies P2(a)=f(a) , p'2(a)= f'(a),and p2''(a)=f''(a) and describes the behaviour of f near a better than any other polynomial of degree at most 2. ============================================================================ 打的好手酸喔，休息一下待會再繼續 -- 簡東甫沒雞雞 -- 海珊總統不愛打仗賓拉登愛好和平納豆不愛泡夜店小雞志從不腦殘你說對吧? 簡東甫有大雞雞! -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 219.68.89.176
