Tan^210° sin ^240° + tan^240° cos^210°/ sin 330° cos 120°

Berikut saya sertakan cara mencari nilai sin, tan, dan cos nya. Masih kurang 1, tidak bisa ikut terfoto :

cos 120
= cos (180-60)
= cos -60
= -1/2

lalu kita hitung :

= (1/2 × -1/2 √3) + (√3 × -1/2 √3) / (-1/2 × -1/2)
= (-1/4 √3) + (-3/2) / (1/4)
= (-1/4 √3) + (-6/4) / (1/4)
= (-6-√3/4) / (1/4)
= (-6-√3/4) × 4/1
= -6-√3

semoga membantu
