思考のプロセス 例 249 点A(1,2)を通り,傾きmの直線を1とする｡ 直線と放物線C:y=x2 で囲まれる部分の面積Sが最小となるような定数mの値, およびそのと きの面積S の最小値を求めよ。 例題 35 H の構図になる。公式の利用 cm Action 放物線と直線で囲む面積は、 f(x-a)(x-B)dx=-1/2(B-c) を用いよ 19255 開 点 A(1,2) は放物線Cの上側の点であるから,放物線Cと 直線は異なる2点で交わる。 直線の方程式はy=m(x-1)+2であるから, 放物線y=x2 との交点のx座標は x=m(x-1)+2 あんま。 Cとlの方程式を連立すると,α,β は複雑。 直接 β-αを求める。 (B-a)³ → 解と係数の関係から考える。 すなわち x-mx+m-2=0 の実数解である。 2つの実数解を α, β(a <β)とすると ( S= = "{m(x-1)+2-x)dx = - S₁ (x² - m² (x2-mx+m-2)dx ゆえに - ₁²(x − a) (x − B) dx = 1/(B − a) ³) == ここで解と係数の関係より aβ=m-2 (B − a)² = (a + ß)² − 4¤ß =m²-4m+8 a+B=m, したがって, S は m=2のとき 最小値 = (m−2)² +4 α<β より,β-α>0 であるから, β-αは m=2のとき 最小値 √4 = 2 23 6 = VA 430 2 α 0 y=x2 1β 判別式をDとすると D = m²-4m+8 = (m-2)^²+4>0 y-2=m(x-1) x-mx+m-20 を実 際に解くと x= m± √√m²-4m+8 2 であり B-a = √√m²-4m+8 =√(m−2)2+4 よって, β-αはm= のとき 最小値 √4 = 2 と考えてもよい。

[4] Read the instructions and write a well-organized answer in English. (50 points) Virtual reality (VR)* refers to a high-quality simulation of reality created by a computer. Probably the most famous use for VR so far is gaming. But VR has also been used to improve society in various fields such as education, medicine, and engineering. Describe a single specific way that virtual reality can be used to improve society. Explain your idea in detail in about 100 English words. Notes: Virtual reality (VR)*: VR systems use special glasses that completely cover the user's eyes. These glasses show a very realistic picture of a world created by the computer. In addition, the systems can tell when the user moves their head, arms, and sometimes other body parts. So users can control the action by natural movement. Some systems even let users feel like they are touching things. Thus, VR systems can make users feel like they are really in another world. 〔答案〕 I suggest you to simulation with VR. For example, doctors can practice operation. I have the three reasons. First, VR's display is very real. So doctors can do as if real simulation. Second, every one can make simulation software. If you want add patients information to VR and study how to make software, you can make VR software to yourself. Third, medical professors can use VR simulation in lecture. If they do this, Students who want be surgeon in the future will reduce about operation's anxiety. In this way, VR have a lot of possibilities that useful of medical field. For these reasons, I suggest VR simulations.

In 2015, another survey asked 15-year-old students in 48 countries and regions about their life satisfaction. They answered on a scale of 0 (not satisfied at all) to 10 (completely satisfied). Look at the table. In Japan's score was 6.80. This was well below the average of 7.37. Japan ranked sixth to last. Other Asian students also showed low levels of life satisfaction. Asia, there are many places where society emphasizes academic results. This social pressure may explain the lower satisfaction of Asian students.
