Kakak2 penghuni brainly tolong fast responnya yya! Nilai dari cos 210* Tan 240* Sin 315* Cos 300* Please fast respon nyya..!☺

Cos 210° = cos (180 +30)° KD III cos (-)
= - cos 30°
= -1/2 akar 3

Tan 240° = tan (180 +60)° KD III tan (+)
= tan 60°
= akar 3

Sin 315° = sin (360-45)° KD IV sin (-)
= - sin 45°
= - 1/2 akar 2

Cos 300 = cos (360-60)° KD IV cos (+)
= cos 60°
= 1/2
