To find the reasons, I set up a table at a large building and offered two kinds of chocolates-high-quality and ordinary ones. 2. There was a large sign,"One kind of chocolate per customer." 3. We also set the price of the high-quality chocolates at 15 cents, which was cheaper than the regular price, and the ordinary ones at one cent. 4. Our customers acted with a good deal of rationality: 5. they compared the price and quality of the chocolates and about 73% of them chose the high-quality chocolates and 27% chose the ordinary ones. 6. Next we decided to see how "FREE!" might change the situation, so we offered the high-quality chocolates for 14 cents and the ordinary ones for free. 7.

不定方程式についての質問です。(1)のような問題が来た場合、手当り次第数字当てはめて行くしかないってことですか、?

246 第9章 基礎問 147 不定方程式 ax+by=c の解 Lead yを整数とする. 方程式 2x3y=7・・・・・・ ① について,次の問いに答えよ. (1) ①をみたす (x,y) の1組を見つけよ (1)(x,y) を (α, β) とするとき, 2α-3β=7. ②が成り たつ ①,②を利用して,r-αは3の倍数で,y-β は2の倍数で なあることを示せ . (3) ①をみたす (x, y) をすべて求めよ. (4) ①をみたす (x, y) に対して, r'-y2 の最小値とそのときの x, yの値を求めよ. |精講 ax+by=c(a,b,c は整数でαとは互いに素)をみたす (x, y) を求めるとき,この基礎問の(1)~(3)の手順に従います。 (1) 未知数2つ, 式1つですから, (x, y) は1つに決まりません. すなわち,たくさんあるということです. その中から、何でもいいから1組 見つけなさいということです. (2)x-a や y-β をつくるためには,①-②をつくるしかありません.J (3) -αは3の倍数だから, x-α=3n (n: 整数) とおけます. もちろん,(α,B) は(1)で決めた値です. (4)(3), x,yを1変数nで表しているので,x-y' もんで表せます. (1)x=2,y=-1 とすると, 2x-3y=2・2-3・(-1)=7 よって、 ①をみたす (x, y) の1組は (2,-1) 注 このほかにも(x,y)=(5, 1), -1, -3) などがあります。 (2) 2x-3y=7. ① 2a-3β=7... ② ①-②より2(エーα)=3(y-B)

赤い下線のところがどういう構造になっているか分からないです、教えてくださいm(_ _)m

moving from " (1) 点) There are historians and others who would like to make a neat division between "historical facts" and "values." The trouble is that values even enter into deciding what count as facts-there is a big leap involved in 'raw data" to a judgement of fact. More important, one finds that the more complex and multi-levelled the history is, and the more important the issues it raises for today, the less it is possible to sustain a fact-value division. But this by no means implies that there has simply to be a conflict of prejudices and biases, as the data are manipulated to suit one worldview or another. What it does mean is that the self of the historian is an important factor. The historian is shaped by experiences, contexts, norms, values, and beliefs. When dealing with history, especially the sort of history that is of most significance in philosophy, that shaping is bound to be relevant. As far as possible it needs to be articulated and open to discussion. The best historians are well aware of this. They are alert to many dimensions of bias and to the endless (and therefore endlessly discussable) significance of their own horizons and presuppositions. A great deal can of course be learned from those who do not share our presuppositions. Our capacity to make wise, well-supported judgements in matters of historical fact and significance can only be formed over years of discussion with others, many of whom have very different horizons from our own. It is possible to I have a 12-year-old chess champion or mathematical or musical genius, but it is unimaginable that the world's greatest expert on Socrates could be that age. The difficulty is not just one of the time to assimilate information; it is (2)
