写真のマーカーの問題が分かりません！！ 答えはis comingです。 なぜ、現在進行形の形になるんですか？？ comesじゃなぜダメなんですか？？？

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

ing形が形容詞的用法はダメな方法が説明されてるのですが、この説明の意味がよくわからないです。今泳いでる人と一緒に触れ合ってるイルカが我々に語ってくれる話？？子供達が語ってくれる話？？名詞的用法と違うところあるかな？って思いました、

3. Answer the following questions. 1 What is the difference between UNIX and Linux? 2 3 4 Choose one of the words in italics in the text. What is the definition of the word you have chosen? What are the three levels of a Linux system? What are the two main functions of the kernel? [Reading Text] UNIX was initially developed by researchers at Bell Labs in the 1970s. Today, UNIX and its variants are widely used mainly on servers. By far, the most well- known UNIX-like operating system is Linux. Linux is available in different distributions which include the Linux kernel and different collections of software. These distributions have various user interfaces, many experienced users preferring the command-line interface, or shell. Linux distributions include a range of software including text editors. memory. While the mechanics of Linux and other Unix operating systems are complicated, the components of a Linux system can be grouped into three levels. The lowest level is the hardware, such as Central Processing Unit (CPU) and The next level is the kernel. It enables communication between hardware and software, by providing instructions to the CPU and other hardware. The programs that are running on the system, or processes, make up the top level known as the user space. Processes in user space generally only have access to a restricted amount of memory and operations, this is called user mode. The kernel runs in kernel mode which allows it unrestricted access to hardware resources. The kernel provides functions such as process management and memory management. A computer only has limited Random Access Memory (RAM) and processor cores. Process management allows the system to run multiple programs (processes) at the same time even if the CPU can only execute only a few processes at a time. Memory management allows applications to share the system's memory while avoiding potential issues such as memory leak. Included with the kernel are device drivers that provide an interface for applications to communicate with hardware, such as hard drives. System calls allow user processes to access features that are executed at kernel mode, for example creating new processes.
