Hitunglah nilai rasio trigonometri ini dalam rasio sudut lancip A: cosec 330celcius B. Secan 315 Celcius

1. Cosec(330)= 1/sin(330)
   
Sin(330)= -sin(30)= -1/2

Cosec(330)= -2

2. Secan(315)= 1/cos(315)

cos(315)= - cos(45)= [tex]- \frac{ \sqrt{2} }{2} [/tex]

Sec(315)= [tex]- \frac{2}{ \sqrt{2} } [/tex]
