Find the value of $ arcsin(sqrt{3}/2) $ based on the unit circle

Answer 1

Abigail Nelson

Isabella Walker

To find the value of $ \arcsin(\sqrt{3}/2) $, we need to locate where $ \sin(x) = \sqrt{3}/2 $ on the unit circle.

On the unit circle, $ \sin(x) = \sqrt{3}/2 $ at the angles:

$ x = \frac{\pi}{3} $

and

$ x = \frac{2\pi}{3} $

So,

$ \arcsin(\sqrt{3}/2) = \frac{\pi}{3} $

in the primary range of arcsin, which is $ [ -\frac{\pi}{2}, \frac{\pi}{2} ] $.

Joseph Robinson

To determine $ arcsin(sqrt{3}/2) $, we look for the angle $ x $ where $ sin(x) = sqrt{3}/2 $ within the interval $ [-frac{pi}{2}, frac{pi}{2}] $.

The value of $ sin(x) = sqrt{3}/2 $ occurs at:

$ x = frac{pi}{3} $

Thus,

$ arcsin(sqrt{3}/2) = frac{pi}{3} $

John Anderson

To find $ arcsin(sqrt{3}/2) $, locate where $ sin(x) = sqrt{3}/2 $ on the unit circle, which is:

$ x = frac{pi}{3} $

Therefore,

$ arcsin(sqrt{3}/2) = frac{pi}{3} $
