Question

Explain why #4 is A.

Answer 1

I have no idea...where is #4

Answer 2

\[\sin ^{-1} \sqrt{3}/2\]

Answer 3

the inverse sin of a value is a measurement of an angle so

the sin of some angle = \[\frac{\sqrt{3} }{ 2 }\]

Answer 4

\[\sin \frac{ \pi }{ 3 } = \frac{ \sqrt{3} }{ 2 } \]
this will occur a full revolution from \[\frac{ \pi }{ 3 }\]
which will happen at \[2 \pi from \frac{ \pi }{ 3 }\]
\[2 \pi * n \] will be n revolutions around the circle and always land on \[\frac{ \pi }{ 3 }\]

Answer 5

I hope that makes sense...
