解

展開する

se x (csc (x) + sin (x)) + cos (x) (sec (x) + cos (x)) + 1

es x csc (x) + es x sin (x) + cos (x) sec (x) + cos^{2} (x) + 1

解答ステップ

se x (csc (x) + sin (x)) + cos (x) (sec (x) + cos (x)) + 1

= es x (csc (x) + sin (x)) + cos (x) (sec (x) + cos (x)) + 1

拡張

se x (csc (x) + sin (x)) : es x csc (x) + es x sin (x)

= es x csc (x) + es x sin (x) + cos (x) (sec (x) + cos (x)) + 1

拡張

cos (x) (sec (x) + cos (x)) : cos (x) sec (x) + cos^{2} (x)

= es x csc (x) + es x sin (x) + cos (x) sec (x) + cos^{2} (x) + 1
