新高1です。 数学Ⅲの微分法で漸近線を求める時に、X→∞に近づけたり、X→a±0に近づけたりと、①.②.③の使い分けが分かりません。誰か親切な方教えてくれませんか?😆

数学Ⅲで扱う関数のグラフは,漸近線をもつものも多い。ここで,漸近線をどのよう 漸近線の求め方 して求めればよいかについて説明しておく。 [画 曲線 y=x+1+ ここで, -x=1+ x→±∞のとき x-1 直線y=x+1 に近づいていく。 これが漸近線の1つである。 また, x1±0のとき したがって、 について →0であるから曲線は 一般に,関数y=f(x)のグラフに関して,次のことが成り立つ。 ① x軸に平行な漸近線 limf(x) =α または lim f(x) =α ⇒直線y=aは漸近線。 X-8 x- ② x軸に垂直な漸近線 lim f(x) =∞ または lim f(x) =∞ または lim f(x)=∞ xb+0 x→b+0 x→b-0′ lim f(x)=-∞ ⇒直線x=b は漸近線。 xb-0 X y →±∞ (複号同順) 直線x=1 も漸近線である。 軸に平行でも垂直でもない漸近線 lim{f(x)-(ax+b)}=0 または lim {f(x)-(ax+b)}=0 X→∞ ここで、③に関し, a, b は α=lim より求められる。 Ital [説明] 漸近線は, 曲線上の点P(x, f(x)) が原点から無限に遠ざかると き,Pからその直線に至る距離PHが限りなく小さくなる直線である。 直線y=ax+bが曲線y=f(x) の漸近線で,Pからx軸に下ろした 垂線と,この直線との交点を N (x,y) とする。 PHPNは一定であるからPH→0のとき PN=1f(x)-y|=|f(x)-(ax+b)| = |x1|1(x)-a-1 | b ⇒直線y=ax+6は漸近線。 f(x) →0であるから また, f(x)-(ax+b) →0であるから なお、上の例の曲線では,x → ±∞のとき x→±∞ 9 435\>x>0 (020) (0) →0(x→または-∞) f(x) b=lim{f(x)-ax} を計算することに 8 a → 0 すなわち f(x) -ax→b y=1+ x 1 f(x) + → a - YA または O 0 ya 1, 1 - 1 であることからも, 直線y=x+1が漸近線であることがわかる。 x(x-1) y=f(x)/ P (x, f(x)) Ⓒy=ar-i H N(x, J

Masters of the Desert “Bedouin” is a name given to some of the people who live in North Africa and the Middle East. Unlike most people, many Bedouins do not ( 24 Instead, they are nomads, which means that they are always moving about. They walk around the hot deserts of countries like Egypt and Israel, leading their camels and sheep to gras and water. Life in the desert is not easy, but over thousands of years, Bedouins have developed unique skills to help them survive. Some people estimate that there are around 20 million Bedouins in the world today. However, ( 25 ). Because many of them are traveling, it is impossible to count them all. In recent years, however, many Bedouins have given up their traditional way of life. This is because the amount of land controlled by governments has increased, which has made it harder for the Bedouins to travel freely. Some of them now live in urban areas and have regular jobs, such as driving taxis and working in restaurants. Some Bedouins have found work with the Israeli army as trackers. A tracker is a person who follows people by using signs left on the ground, such as the marks left by feet or tires. Trackers must know their environment well and be quick to notice anything unusual. ( 26 ), with their desert survival skills, Bedouins are excellent trackers. About 1,600 of them are now serving in the Israeli army, and their ability to notice dangers along Israel's borders is helping to protect the countily. 1 sleep lying down 2 live in one place 3 eat meat or fish 4 use paper money 1 their exact numbers are unknown 2 there were many more in the past 3 the groups have no government 4 they all meet once every year 1 Naturally 2 Occasionally 3 Secondly 4 Equally
