解説をみても理解できなかったので教えてください🙏

13002 のとき, 関数 のときの8の値を求めよ。 y=2sin2+2cos0+4 の最大値と最小値を求めよ。 また, そ

解説をみたのですが分からなかったので教えてほしいです！

>0 (6) cos(20+) = 12/201

これの場合の連立する解き方を教えて下さい

266 から sin 0>0, (1) (sin @-cos 0)=sin 0-2sin 0 cos 0 + cos² 0 =1-2sin 0 coso -1-2-(-)- 3 sin 00, cos00より, sincos! >0で あるから 5 sin 0 - cos 0 = 3 √15 3 (2) (sin+cos0)=sin 20+2sin / cos0 + cos20 =1+2sin0cos0 1 =1+2・ - 3 したがって sin0 + cost = 土、 (3)(2)から 3 = : 1 √3 √3 √3 sin+coso または = sin+coso -- 3 √3 ② のとき,①,②を連立して解くと sin 0 = <15+√3 6 √15-√3 cost=- 6 ③ のとき, 1, ③を連立して解くと √15-√3 √15 +√3 sin 0 = = cos == 6 6 したがって √15 +√3 sin = または sin = 6 √15 -√3 6 √15-√3 cos 6 √15 +√3 cos 0 = 9 6

こうなる変形の途中式を教えて欲しいです🙇‍♀️

(excosx) (ex sin x) -2e cost {e-* (sin x-Losx)) = e^x ios x -π
