Tentukan nilai trigonometri berikut
Cos 330
Tan 120
Cos 150
Tan 330
Cosec 135​

Penjelasan dengan langkah-langkah:

Kuadran IV

[tex] \cos(330°) \\ = \cos(360° - 330°) \\ = \cos(30°) \\ = \frac{1}{2} \sqrt{3} [/tex]

Kuadran II

[tex] \tan(120°) \\ = \tan(180 - 120°) \\ = - \tan(60°) \\ = - \sqrt{3} [/tex]

Kuadran II

[tex] \cos(150°) \\ = \cos(180° - 150°) \\ = - \cos(30°) \\ = - \frac{1}{2} \sqrt{3} [/tex]

Kuadran IV

[tex] \tan(330°) \\ = \tan(360° - 330° ) \\ = - \tan(30°) \\ = - \frac{1}{3} \sqrt{3} [/tex]

Kuadran II

[tex] \csc(135°) \\ = \csc(180° - 135°) \\ = \csc(45°) \\ = \frac{1}{ \sin(45°) } \\ = \frac{1}{ \frac{1}{2} \sqrt{2} } \\ = \sqrt{2} [/tex]
