Math Problem Statement

Find the value of sin^(-1)(√3/2).

Solution

The given mathematical expression is sin1(32)\sin^{-1}\left(\frac{\sqrt{3}}{2}\right), which represents the arcsine or inverse sine function.

To solve this:

  1. Recall that the sine of an angle gives the ratio of the opposite side to the hypotenuse in a right triangle. The arcsine function sin1(x)\sin^{-1}(x) gives the angle θ\theta whose sine is xx.

  2. From the unit circle: sin(π3)=32.\sin\left(\frac{\pi}{3}\right) = \frac{\sqrt{3}}{2}.

  3. Therefore: sin1(32)=π3.\sin^{-1}\left(\frac{\sqrt{3}}{2}\right) = \frac{\pi}{3}.

The solution is: π3\boxed{\frac{\pi}{3}}

Tip:

When working with inverse trigonometric functions, always consider their principal branches, which determine the range of possible solutions. For sin1(x)\sin^{-1}(x), the range is [π2,π2][-\frac{\pi}{2}, \frac{\pi}{2}].
