手書きのやつが私の答案なのですが、極形式で表したときいつもθについての範囲を0<=θ<2πにしているので今回もθの範囲をそうして、図をかいて題意を満たす式をだしたのですがこのような書き方ってあってますか？最初からθの範囲を題意に合うようにπ/2<θ<πとしなければいけませんか？

（4）の最後の部分が微妙にちがうのですが、これって正解ですよね？普通に場合分けしたらおなじになるので、、

この文脈から、なぜ店員が狼狽していると思われるのですか。

popped up where I least expected them. The most surprising might have been whenI ordered green tea with sugar at a restaurant. After a pause, the waiter politely explained that one does not drink green tea with sugar. I responded that yes, I was ア of this custom, but I liked my tea Sweet. My request was met with an even more courteous version of the same explanation: One does not drink green tea with sugar. While I understand, I told him, that the Japanese do not put sugar in their green tea, I would still like to put some in my green tea. Frustrated, the waiter took up the issue with the manager, and the two of them began a lengthy Conversation. Finally, the manager came over to me and said, “I am very sorry. We do not have sugar.” Since I couldn't have the green tea as I liked it, I changed my order to a cup of coffee, which the waiter soon brought over. Resting on the saucer were two packets of sugar.
