Question

Sebutkan rumus trigonometri

Answer 1

Ini jawabanyaaa moga membantuuu 

Answer 2

1. 360° = 2π radian
π radian = 360°/2 = 180°
Jadi, π radian = 180°
2. 1° = π /180° radian
= 3,14159/180 radian
Jadi, 1° = 0,02 radian
3. 1 radian = 180°/π
= 180/3,14159
Jadi, 1° radian = 57,296° atau 57,3°
1. Sin 0° =
0
Sin 30° = 1/2
Sin 45° = 1/2 √2
Sin 60° = 1/2 √3
Sin 90° = 1
2. Cos 0° = 1
Cos 30° = 1/2 √3
Cos 45° = 1/2 √2
Cos 60° = 1/2
Cos 90° = 0
3. Tan 0° = 0
Tan 30° = 1/3 √3
Tan 45° = 1
Tan 60° = √3
Tan 90° = ∞
4. Cosc A = 1/sin A
Sec A = 1/Cos A
Cotg A = 1/Tg A
