If ( \theta= -\frac{13\pi}{6} ), what is its reference angle?यदि ( \theta= -\frac{13\pi}{6} ) है तो उसका संदर्भ कोण क्या है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: ( \frac{\pi}{6} )( \frac{\pi}{6} )
( -\frac{13\pi}{6}+\frac{24\pi}{6}=\frac{11\pi}{6} ), and the reference angle is ( \frac{\pi}{6} ). First bring the negative angle into (0) to (2\pi).( -\frac{13\pi}{6}+\frac{24\pi}{6}=\frac{11\pi}{6} ) और संदर्भ कोण ( \frac{\pi}{6} ) है। ऋणात्मक कोण को पहले (0) से (2\pi) में लाएं।
