（1）の定積分の問題なのですが、aとおいたあとの式までは理解できるのですが、その後どうして解答の2行目のような式になるのかが理解できません。教えて頂きたいです。

378 (1) f(x)=6x-x+S_f(t)dt 次の等式を満たす関数 f(x) を求めよ。 基本 例題 241 定積分で表された関数 (2) f(x)=f(x+1)s (d+) 000 Sdt-a. Su よって Sof(t) 指針 (1) f(x)はこれから求めようとする関数なので,定積分f(t)dt を計算するこ Sit -1 =FD-F また できない。ここで,F(x)=(x)とすると, S., であるから,S,f(t)dt は定数である。 よって、f(t)dt=a (a は定数) とおくと, f(x) =6x-x+αと表される Stadt=aである。この定積分を計算しての値を求める。 (2)f'(x+1)(0) は変数を含むから、f(x+ff(e)dr=(定数)とおくこと ない。そこで、まずはf(x+1)f(t)de=S,xf(t) dt+Sザ(t)dt と変形する。 そして、Soxf(edt において,xは積分変数に無関係であるから」の前に とができ、S'(x+1)f(t)dt=xff(t)dt + Suf(t) dt と変形できる。 Sof(t) dt と Sof(t) dt は異なる定積分であるから,それぞれを別の文字(定数 おく。 ゆえに よって これを解い したがって 定積分の扱し (1)S_f(t)dt=a とおくとf(x)=6xx+α (2) について 検討 × 積分 × 解答 よってS,f(t) dt=S(6t-t+a)dt ゆえに よって したがって (2) =2S(6t+a)dt =2[21³+at] =2(2+α) 2(2+α)=a a=-4 f(x)=6x2-x-4 S'(x+1)f(t)dt=Soxf(t)at+Soff(t)dt x は積分変数 tに無関係であるから Sxf(t)dt=xf(t)dt(s) ゆえに f(x)=xff(t)dt+Souf(t)dt+1 Sot ① S の定積分 -a 偶数次は25 また、> 奇数 0 定積分の S,f(t)dt=aから。 f(x)=6x2-x+a S'(x+1)f(nat f(x)+ xは定数として扱い 積分の前に出す。 練習 次の (1) ②241
