よく分からないので詳しく教えてくださいっ
90度ーθの三角比とどう違うのか教えてくださいっ
そもそも何で座標を用いていているんですか?
(⑧ 90*十の の三角比 (0*s9s90*)
Sin(90*十の)=cos9
cos(90*十の=ーsinの9
tan(90*+の=ー-ユエー (9@キ0*,。9=90)

②
メん でHHC
。in(90'†すの=sint180"-(9-の)
ーーsin(90*一の=cos9 <
cos(90"十の三cost180*一90の)
テーcos(90"一の=テーsin9
tan(90"-
Fのtan(180*一(90*一の)}
ニーtan(90"一の=ニーーニー
