Question

${sin}^{ - 1} \: (sin \frac{2 \pi}{3})$
solve fast​

Answer 1

Answer:

$\tt\huge \implies: \frac{ \pi}{3}$

Step-by-step explanation:

$\tt\ \: {sin}^{ - 1} (sin \frac{2 \pi}{2}) \\ \\ \tt\ \implies: {sin}^{ - 1}[sin( \pi \: - \frac{ \pi}{3} )] \: \: \: \: \: \: ( \because \: \frac{2 \pi}{3} \notin \: [ \frac{ - \pi}{2}, \frac{ \pi}{2} ]) \\ \\ \tt\ \implies: {sin}^{ - 1}(sin \frac{ \pi}{3}) \\ \\ \tt\huge \implies: \frac{ \pi}{3}$
