dx=a・cosθ・dθだと思います
次の行でもdθが抜けていてその次の行からdθがついています
あと、板書のtanxをsinxで割ったのは1/cosxの書きミスかなと思いました
この例3の解き方が循環論法でNGだというのはすごく勉強になりました。知らなかったらこれからもずっとこの方法で解いていたと思います。ありがとうございます。
個人的に循環論法の話は、あれに限ればそうならない証明ができるので、一概にダメとしてはいけないと考えます。(極限の証明からさせる問題であれば主張は理解できますが。)
直線QYと直線PXがねじれの位置にあるための必要十分条件を聞かれているのに，答案例では直線QYと直線PXがねじれの位置であることを前提として全てのx,yで題意を満たすと言っている．
一次独立の話よりも根本的なところに誤りがあって誰も指摘していないのは意味が分からない．
なお答えは答案例の論法を修正して利用すれば，(s, t)=( 2-2y, 1 )の時に点PQXYが同一平面上にあるので，x≠yが必要十分条件．
a[n] = 111…1 → …111 = -1 だから、α = 2α+1 で良いのではないだろうか？
もし、この動画の趣旨が「循環論法であり、間違いだから、大学受験では×にされる。だから、他の方法でやれ」ということであれば、高校生が理解でき、かつ、試験場で再現できる方法はどのようなものなのでしょうか？
マクローリン展開から容易に証明できる方法があることを知ってるとそれで良いのでは？
面積を用いる証明方法が唯一であるという前提があるようにも思います。
