Math Problem Statement

arc sin(root3/2)

Solution

The value of arcsin(32)\arcsin\left(\frac{\sqrt{3}}{2}\right) is the angle whose sine is 32\frac{\sqrt{3}}{2}. In the unit circle, the sine of 32\frac{\sqrt{3}}{2} corresponds to an angle of:

arcsin(32)=π3 radians or 60\arcsin\left(\frac{\sqrt{3}}{2}\right) = \frac{\pi}{3} \text{ radians or } 60^\circ

This is because sin(π3)=32\sin\left( \frac{\pi}{3} \right) = \frac{\sqrt{3}}{2}, and the principal value of arcsin\arcsin is restricted to the range [π2,π2]\left[-\frac{\pi}{2}, \frac{\pi}{2}\right].

Here are 5 related questions:

  1. What is arccos(32)\arccos\left(\frac{\sqrt{3}}{2}\right)?
  2. How is the range of the arcsin function determined?
  3. Can the sine of any angle ever be greater than 1 or less than -1?
  4. How would you compute arcsin(12)\arcsin\left(\frac{1}{2}\right)?
  5. What is the general solution for sin(θ)=32\sin(\theta) = \frac{\sqrt{3}}{2}?

Tip: The arcsin\arcsin function always returns an angle in the range [π2,π2]\left[-\frac{\pi}{2}, \frac{\pi}{2}\right].
