この英文の17行目なんですけど、under the control で〜に支配されてと訳すのは分かるんですけど 日本語訳だと、集中力もまた意志に支配されていなければならない。と書いてあって意志という単語は 書かれてないのに、どうしてこういう訳なるんでしょうか?

14 集中力とは何か 10 Besides the intellect, the power of concentration is a very important quality, which few people acquire except throug education. It is true that it develops naturally to some extent, bu people are not likely to acquire enough concentration without a 5 long period of intellectual education. 2 There are three qualities which distinguish perfect concentra tion from imperfect concentration: perfect concentration should be intense, prolonged and voluntary. Intensity is illustrated by the story of Archimedes. He is said to have taken no notice when 10 the Romans came to kill him, because he was absorbed in a mathematical problem and bent on solving it. To be able to concentrate on the same thing for a long time is essential to difficult achievement. As long as the object is of great interest, this is brought about naturally. 15 Most people can work on a mechanical puzzle for a long time; but this is not in itself very useful. To be really valuable, the concentration must also be under the control of the will. I think 18 it is above all the control of the will that is nurtured by education. Check!! concentration () 183 wo

接線の問題です。下線部の言っていることが全く分かりません。分かりやすく説明して欲しいです!

Check 例題 180 第3章 図形と方程式 次 例 題 99 円外の点から引いた接線2 ヴ+y=5 に点(3, 1) から接線を2本引く. そのときの2つの接点 をP, Qとするとき,直線PQの方程式を求めよ。 考え方」 (i) 離れ 考え方 接点の座標を P(x), w). Q(x2. 12) とおいて求める。 解答 接点をP(x), y), Q(x2, Va) とすると, 点Pにおける接線は これが点(3, 1) を通るから, 点Qにおいても同様にして, D, ②より。点P. Qは直線 3x+y=5 上の点である。 2点P, Qを通る直線は1本に決まるので,直線 PQ の方程式は, 円x+y°=r? 上の 点(x), )における接綱 Xx+y=5 3x+y=5 …① 3x2+ y2=5 …2 の方程式 X1x+ yy=r? YA d> 解答 3x+y=5 (別解)点R(3, 1) とする。 るの V5 P AOPR とA0QR は合同な三角 形だから,対称性より, ORIPQ これより,直線PQの傾きは -3 であるから, kを実数として, 直 線 PQは, y=ー3x+k とおける。 0 x Q (直線 OR の傾き) k ×(直線 PQの傾き)=-1 図より,k>0 原点と直線 PQの距離dは、 1- d= 13+1 V10 ここで,直線 OR と直線 PQの交点をSとすると、 AOPRのAOSP であり, OR=/10, OP=/5, OS=→R だから, 15:=/10 V10 <POR : ./ 低重心シャープペン 白·0.3mm BALANCED MECHANICAL PEN.0.3mm H 1 >21 ニ1 v G
