【that】 緑マーカーのthatってなんなんすか? developの目的語ですか? もし違ったらdevelopの目的語ってどれですか?

①English has become the leading international language because of three rather different developments. Firstly, the language acquired a strong position in large parts of the world as as Britain built and maintained its empire from the seventeenth through to the ( A ) twentieth centuries. Secondly, the United States obtained a leading position in technology, economy, and politics in the first part of the twentieth century, and still retains this status. Thirdly, industry, communications, and international relations developed in such a way in the twentieth century that a common language was much more in demand than before. English was there to fill (a) the need, while the other European languages had been pushed aside for different reasons. As the *prominent position of English arises from the three factors mentioned, attitudes towards the language among people outside the English-speaking countries may vary accordingly. English may be seen as a language of communication all over the world, or as a tool for the imperialist ambitions of the United States, or as [ ] *inheritance. All these views are justified to some extent. Different opinions tend to prevail in different parts of the world. In countries outside the direct spheres of influence of the United States and Britain people often stress the advantages of using one international language in contacts with many *linguistic areas. People who speak a small language as their native tongue appreciate that one other language opens up opportunities for contacts in areas. For this reason it is becoming ever more important to learn English as a second language in most countries of the world. B

次の写真でcについて積分定数と言わなくてだ大丈夫なのでしょうか?どなたか解説お願いします🙇‍♂️

例題 235 不定積分〔2〕...∫(ax+b)" dx 次の不定積分を求めよ。 (1) ∫(2x+1)dx 思考のプロセス (2)f(x+1)(x+2)dx (2x+1)(x+1)(x+2) を展開してもよいが, 項が多くなり大変。 |公式の利用 次の公式を用いると, 計算量が少なくなる。 Sax+b)"dx= (1次式)* 1 1 an+1 (ax+b)"+1+C x+1に注目して, (x+1)* をつくる。 (x+1)(x+2) = (x+1)^{(x+1)+1}=(x+1)+(x+1)2 Action》(ax +b)" の積分は, 1 a n+1 -(ax +b)"+1 + C とせよ (2x+1)dx= 1/12 1/2(2x+1)'+C= 1/2(2x+1)^+C 1 (1) ∫(2x 〔別解) (2x+1)dx = (8x3+12x +6x+1)dx ∫(8x + = 2x4+4x°+3x + x + C (2) f (x+1)(x+2)dx = f (x+1)^{(x+1)+1}dx 〔別解) f(x+1) =∫{(x+1)+(x+1)*}dx 1/2(x+1)+1/2 (x+1)^+ 1/2(x+1)+C (x+1)²(x+2)dx = √(x²+2x+1)(x+2)dx = f (x+4x²+5x+2)dx ◆ Point 参照 √(ax+b)" dx 1 1 -(ax + by +1 + C a n+1 例題234のように展開し てから考えてもよい。 (x+1)(x+2) = (x+1)^{(x+1)+1} = = (x+1)+(x + 1) と変形して, 公式を利用 する。 1 4 5 = x4+ + x2+2x+C 4 3 2 Point (ax +b)"の不定積分 nが自然数のとき, {(ax +b)"+1} = a(n+1)(ax+b)" が成り立つから f(ax+b)"dx = 1 1 (ax +b)"+1+C (a = 0) a n+1 この公式は ( 内がxの1次式の場合にのみ利用できる。 ( 内が2次以上 の式の場合は展開してから積分する。
