どうして定義域を広げてもいいんですか?

41点で微分可能にする (x≥1) (x<1) log. 関数f(x)={ ax+b +1 ƒ(x)={9(x) (x<a). lh(x) (a≤x) ・・・・・・・ A x=αで微分可能な条件・・・・・・☆ を考えよう。 定義域を広げておく Aのg(x) の定義域を <a と考える必要はない。 例えばg (r) = sing であ れば全実数で定義されていると考えてよい. いまは, g(x), h (x) が全実数で定義されている微分可 「『能な関数』………◇ と定義域が広げられるとしよう.g(a), g' (a), h (α) を考えられるようになる。 グラフをつなげる 微分可能ならば,当然つなぎ目でグラフはつながり, 連続である. 定義から. x=αで連続⇔ lim f(x)= lim f(x) = f(α) ・・・・・・① が成り立つ 11140 x-α+0 である。 A の場合, ① は lim_g(x) = h (α) と同値で, ◇により, g(α) = h (α) となる. 次に, 微分可能にする x→a−0 x=αで微分可能 ここで,◇のとき, lim がx=1で微分可能であるようなα, bの値を求めよ。 lim 0 +0 Aについて g (α)=h(α) [=f(a)] とする. 定義から,次が成り立つ、 f(x)-f(a) が同じ値に収束 x-a lim x→a−0 f(x)-f(a) x-a f(x)-f(a) x-a ƒ(x)-f(a) =h'(a) xia であるから,◇のとき, Axで微分可能な条件は,αで連続かつ微分係数が一致すること,つ まり, g(a)=h(a)g'(a)= h'(a) -=lim ao =lim と lim x→a+0 x→a+0 (防衛大) g(x)-g(a) x-a h(x)-h(a) x-a -=g'(a),
