Answer:
π/3
Step-by-step explanation:
We have to find the principal value of [tex]\text{arc sin}(\frac{\sqrt{3}}{2} )[/tex]
arc sin means sin inverse. The sin inverse is a one to one function with its range between [tex]-\frac{\pi}{2} \textrm{ to } \frac{\pi}{2}[/tex]
The principal value of the arc sin will lie within the above given range.
value of sin (60) or sin([tex]\frac{\pi}{3}[/tex]) is [tex]\frac{\sqrt{3}}{2}[/tex].
[tex]\frac{\pi}{3}[/tex] lies between [tex]-\frac{\pi}{2}\textrm{ and } \frac{\pi}{2}[/tex]
So, from here we can say that the Principal Value of Arc sin(square root of 3/2) is π/3
