この問題の解き方が解説を見てもよくわかりません。 接線方程式が三次関数でその実数解の個数が接点の個数となることや、極大と極小をかけてマイナスにならなければいけないことが特に分かりません。 教えてください🙇‍♂️🙇‍♂️

3次曲線と接線 199 点(1,0) を通って, 曲線 y=x²+ax2+bx に異なる3本の接線をひくこ とができるような, a, b の条件を求め, 点 (a, b) の存在する領域を図示せよ。 精講 曲線 y=f(x)の接線の方程式は, 接点 (t, f(t)) により決まります. このときの接線の方程式は y=f'(t)(x-t)+f(t) であり,これが点(a, b) を通ることから,t の方 b=f'(t)(a-t)+f(t) .....(*) 程式 を得ることができます.この方程式をみたす t を 求めれば,その点における接線が1本ひけること になります。すると, 3次関数のグラフでは接点 が異なれば接線も異なるので, 接線の本数=接点の個数 =方程式 (*)の実数解の個数 ということになります. y=x^3+ax²+bx y'=3x²+2ax+6 曲線上の点(t,t+at2+ bt) における接線の方程 式は 解答 y=(3t²+2at+b)(x−t)+t³+at² + bt y=(3t2+2at+b)x-2t-at2 これが点 (10) を通るのは 0=-2t+(3-a)t2+2at+b のときである. f(t)=2t³—(3—a)t²—2at-b とおく. 3次関数のグラフでは接点が異なれば接線 も異なるので 点 (10) を通る接線が3本ひける ⇒f(t)=0 が異なる3つの実数解をもつ 解法のプロセス 接線の方程式 y=f'(t)(x-t)+f(t) ↓点(1,0)を通る 0=f'(t)(1-t)+f(t) 225 方程式(*)が異なる3つの実数 解をもつ 接線が3本存在する Ak y=f(t)₁

答えは1です。そのためにはsin^ 20°分の1−cos^2 20°となるだろうということはわかるのですが、それがどうしても導き出せず何が間違っているのかがわかりません、、。

Unit 2 長文問題Ⅱ ミツバチは女社会? 1 Have you ever experienced a bee sting? If you have, you may (1) not be fond of bees. However, they are very interesting and honeybee society is very similar to ours. Let's look at some interesting facts about it. 2 Honeybees live together in groups of 20,000-80,000 in a beehive. This group is call] a colony and the bees in the hive can be categorized into three types: a single queen, tens of thousands of worker bees and hundreds of drones. 3 A queen bee's job is to lay eggs all her life. Each day the queen bee lays around 2,000 eggs. The average lifespan of a queen is three to four years. Does the queen "rule" the colony? No. Her duty is simply egg- laying. In fact, the queen bee has a smaller brain than a worker bee.

They are all female bees but can't lay eggs. A worker bee's life is rather short. They live around 40 days. Their job is to keep the queen bee happy. They do all the work but change jobs as they grow. For about a week after birth, they mainly clean the hive. Sometime between five to sixteen days after birth, they usually take care of the babies and help to build the hive. When they become twelve to eighteen days old, they carry food. After that, they guard the hive entrance. When they are three weeks old, they fly out the hive, pollinate plants and collect food. If you're a drone bee, life is hard. You're [ bear ], live for a month or two, and then die. During that time, you're not a productive member of the hive-you can't collect pollen or help to look after eggs, like worker bees-and you can't even sting anyone.
