Convert −390° into radians.
−13π/6
−11π/6
−7π/6
−15π/6
Answer: A
Solution: To convert degrees to radians, multiply by \(\frac{\pi}{180^\circ}\). Thus, \(-390^\circ\times\frac{\pi}{180^\circ}=-\frac{390\pi}{180}=-\frac{13\pi}{6}\). Trick: Multiply the degree measure by \(\pi/180\) and simplify the fraction.
−390° को रेडियन में बदलिए।
−13π/6
−11π/6
−7π/6
−15π/6
उत्तर: A
हल: डिग्री को रेडियन में बदलने के लिए \(\frac{\pi}{180^\circ}\) से गुणा करें। इसलिए \(-390^\circ\times\frac{\pi}{180^\circ}=-\frac{390\pi}{180}=-\frac{13\pi}{6}\)। ट्रिक: डिग्री के मान को \(\pi/180\) से गुणा करके भिन्न सरल करें।
