この問題において、なぜ私が導いたxの値が誤っているか知りたいです。図で書いても、最大値の時−π/4になると思うんですが。確かに7π/4もありますが

11 [クリアー数学Ⅱ 問題312] 次の関数の最大値と最小値, お y=-sinx+cos x よびそのときのxの値を求めよ。 Xa (0≤x<2π)

この問題についてです。 答えにx＋π/3＝9π/4 とありますが、なぜ3π/4 じゃないんですか？9π/4だとxの範囲外だと思うんですが。

10 [クリアー数学Ⅱ 問題311] など言ルダス 0<x<2πのとき、次の方程式, 不等式を解け。 V3 sin t — cost=1 * ・タル sinx + V3 cosx=√2. なぜ

この問題において合成した後が 2sin（x−π/6)だったんですが、π/6は、5π/6じゃ、なぜダメなんですか？

10 [クリアー数学ⅡⅠ 問題311] なぜ訊 0<x<2πのとき、次の方程式, 不等式を解け｡ 3 sin x – cos x=1 S
