Jawab:
cos 113° = - m
Penjelasan dengan langkah-langkah:
sin 23° = m
cos 113° = cos (90° + 23°)
cos 113° = cos 90° . cos 23° - sin 90° . sin 23°
cos 113° = 0 . cos 23° - 1 . sin 23°
cos 113° = - sin 23°

Jawab:
cos 113° = - m
Penjelasan dengan langkah-langkah:
sin 23° = m
cos 113° = cos (90° + 23°)
cos 113° = cos 90° . cos 23° - sin 90° . sin 23°
cos 113° = 0 . cos 23° - 1 . sin 23°
cos 113° = - sin 23°
cos 113° = - m
Jawab:
sin 23° = m
cos 113° = cos (90° + 23°)
cos 113° = cos 90° . cos 23° - sin 90° . sin 23°
cos 113° = 0 . cos 23° - 1 . sin 23°
cos 113° = - sin 23°
