Find the Exact Value sin(300) | Mathway

For memorising cos 0°, cos 30°, cos 45°, cos 60° and cos 90°. Cos is the opposite of sin. We should learn it like. cos 0° = sin 90° = 1. cos 30° = sin 60° = √3/2. cos 45° = sin 45° = 1/√2. cos 60° = sin 30° = 1/2. cos 90° = sin 0° = 0. So, for cos, it will be like.

Kuadran II (90° < α < 180°) sin (180° - α) = sin α cos (180° - α) = -cos α tan (180° - α) = -tan α Hasil dari sin 30° + sin 150° yaitu: sin 30°?...

Nilai dari 8 cos 82,5 . Sin 37,5 - Brainly.co.id

Berdasarkan perkalian fungsi trigonometri nomor 2, maka bentuk soal menjadi : 8 cos 82,5° . cos 37,5° = 4 ( 2 cos 82,5° . cos 37,5° ) Maka penyelesaiannya adalah ; 4 ( 2 cos 82,5° . cos 37,5° ) = 4 ( cos ( 82,5° + 37,5° ) + cos ( 82,5° - 37,5° ) ) = 4 ( cos ( 120° ) + cos ( 45° )
