Tentukan hasilnya setelah di konveksi ke satuan radian.
A) 60° + 30°
B) 120° + 330°
C) 150° + 240°
A) 60° + 30°
B) 120° + 330°
C) 150° + 240°
Jawaban:
[tex]1° = \frac{\pi}{180° } \\ jadi \\ a) \: 60° + 30° = 90° \\ = 90° \times \frac{\pi}{180} \\ = \frac{1}{2} \pi \\ b) \: 120° + 330° = 450° \\ = 450° \times \frac{\pi}{180° } \\ = \frac{5}{2} \pi \\ c) \: 150° + 240° = 390° \\ = 390° \times \frac{\pi}{180° } \\ = \frac{13}{6} \pi[/tex]
