英語の質問です! 画像の(画像暗くてすみません💦)の赤線引いた所の文で、「bags'」と書いてあるのですが、なぜbag'sではないのですか? 教えて頂けると有り難いです!m(_ _)m

to the city. Can we do anything to make foreign tourists more interested in our city?" Mary, one of the but only a few foreign tourists come members from Australia, said, "Why don't we make a video about Hikari City in English?" All the members said, "( ↑ )" The leader said, "OK. Let's make a great video and ask the staff members in Hikari City Hall to use it on their website." Then, three members went to Hikari Castle to get information and two members visited Hikari Flower Park to know more about it. Ryota and Mary were talking about Hikari Sunday Market. Mary said, "We can see the market in front of Hikari Station every Sunday. One of my classmates told me about it when I came to this city from Australia last year. I like talking with local people there. We can eat local food." Ryota said, "That's great. We can find something interesting there for our video. Can you go there with me this Sunday?" She said, "Of course." On the Sunday morning, Ryota and Mary went to Hikari Sunday Market. There were about fifteen stands and some people were buying products there. Mary said, "Look, that is my favorite stand." A woman at the stand was selling juice and cookies. Mary said to her, "Ms. Tanaka, the carrot cookies! bought last week were delicious. What do you recommend today?" The woman smiled and said, "Thank you, Mary. How about fresh tomato juice?" Ryota and Mary had the tomato juice and Ryota said, "Wow. it's delicious. How did you make this delicious juice?" Ms. Tanaka said, "Well, I use my mother's fresh tomatoes. She is a farmer in this city and picks them early in the morning every day." Ryota said to Ms. Tanaka, "I really love this juice." After saying goodbye to Ms. Tanaka, Mary found a new stand. She said, "Look at the stand which sells bags. They are so cute." Ryota agreed and said to Mr. Ito, the man in the stand. "Did you design them?" Mr. Ito said, "Yes. I designed them and the bags cloth is made in Hikari City." Ryota said, "Sounds interesting." Ryota and Mary walked around the market and enjoyed spending time there. 三重県'23年 英語 問題 (5)

図とか書いても 解答の ここで、のあとの解説が理解できないです、、 どなたか一から教えて欲しいです

72 第2章 関数 ( 1変数 ) 重要 例題 016 逆三角関数の性質 sin(Sin't+Cos't) = 1 を示せ。 指針 逆三角関数 Sin't Cost の定義を確認する 問題である。 これらはどちらも、閉区間 (0<x) (1) mil 重要 y4 関数 f の lim n→∞ [-1, 1] 上で定義された連続関数である。 そし て, Sin' は値域が [一であり、 Sin 11 0 x 0 指針 必 Cos t Cos't は値が [0, π] である。 これらを踏ま えて三角関数の定義と照らし合わせると, -1 解答 1 Sin' Cost がどこの角度を測っているか。 が、図のようにわかる。 [1] ここでは,tの符号によって角の測り方が変わるから三角関数の加法定理 sin(a+β)=sina cos β+ cosasinβ を使って機械的に解こう。 CHART 逆三角関数 三角関数の逆関数 x=siny y=Sin ¹x x=cos y y=Cos¹x x=tany⇔y=Tan'x 解答 加法定理により sin(Sin 't+Cos-lt)=sin(Sin't)cos(Cos-lt)+cos (Sin-1t)sin (Cos-'t) =t2+cos (Sin't) sin (Cos 't) 77 ここでより, cos(Sin-lt) 20であるから cos(int)=√1-sin'(Sin't)=√1-ゼ また,Costaより, sin (Cos 't) 20であるから を作 sin Cost)=√1-cos" (Cos 't)=√1 よって sin(Sin't+Cost)=t2+(√1-t2)=1 参考例えば, t>0 の場合, Cost と Sin't は, それぞれ右で図示され 角度を与える。 の正の向きから時計回りに測った角度である。 ただし Cos-'t は x 軸の正の向きから反時計回りに、Sin't y tsug y Mint Cost この図から、閉区間[0, 1] 上のすべての実数に対し、 Sin' + Cos = 2 となることがわかる。 0 t1x したがって sin(Sin-'t+Cos^'t)=sinz=1
