Question

find the value of sin 2×22/7/3​

Answer 1

Answer:

Here if $\frac{22}{7}$ is a fraction which is divided by 3, then its solution will be given as below.

$2 \times \frac{22}{ \frac{7}{3} } \\ = 2 \times \frac{22}{7 \times 3} \\ = \frac{44}{21} \\ = 2 \frac{2}{21}$

Here if $\frac{7}{3}$ is a fraction and 22 is divided by it, then its solution will be given as below.

$2 \times \frac{22}{ \frac{7}{3} } \\ = 2 \times \frac{22\times 3}{7 } \\ = 2 \times\frac{66}{21} \\ = \frac{132}{21} \\ = 6\frac{6}{21} \\ = 6\frac{2}{7}$

Answer 2

Answer:

=> sin 2π/3

=> sin 2 × π/3

=> sin 2 × 60°

=> sin 120°

=> sin(90° + 30°)

=> cos 30°

=> √3/2 Ans.
