cepat di jawab ya sama cara caranya soalnya hari ini udah di kumpul cosec 30 + cosec 60 +cosec 90 sec 0 + sec 60 + sec 60

Kelas 10 Matematika
Bab Trigonometri

cosec 30° + cosec 60 + cosec 90° . sec 0° + sec 30° + sec 60°
= 1/sin 30° + 1/sin 60° + 1/sin 90° . 1/cos 0° + 1/cos 30° + 1/cos 60°
= 2 + 2/3 √3 + 1 + 2/3 √3 + 2
= 5 + 4/3 √3
