Find the exact real value of arcsin. the quantity square root of three divided by two. (-√3/2)?
Solution:
Given, arcsin(-√3/2)
arcsin(-√3/2) is the angle whose sine is -√3/2.
As sine is negative in third quadrant and fourth quadrant
sin(π/3) = √3/2,
we have sin(π - π/3) = -√3/2.
sin(π + π/3) = -√3/2
arcsin(-√3/2) = 2π/3 or 4π/3
Adding or subtracting 2π does not affect trigonometric ratios of angles as they are all coterminal angles.
We can have infinite solutions given by
(2n + 1)π ± π/3, where n is an integer.
Therefore, the exact real value of arcsin is -π/3.
Find the exact real value of arcsin. the quantity square root of three divided by two. (-√3/2)?
Summary:
The exact real value of arcsin the quantity square root of three divided by two (-√3/2) is -π/3.
