Sagot :

To determine which value is equivalent to [tex]\(\sin^{-1}(0)\)[/tex], we need to understand what [tex]\(\sin^{-1}(x)\)[/tex] represents. The notation [tex]\(\sin^{-1}(x)\)[/tex] represents the inverse sine function, also known as arcsine, which returns the angle whose sine is [tex]\(x\)[/tex].

In this case, [tex]\(\sin^{-1}(0)\)[/tex] means we are asking for the angle [tex]\(\theta\)[/tex] such that [tex]\(\sin(\theta) = 0\)[/tex].

Let's consider the possible candidates:

1. [tex]\(0\)[/tex]: Check if [tex]\(\sin(0) = 0\)[/tex]:
[tex]\[ \sin(0) = 0 \][/tex]
This is true, so 0 is a candidate.

2. [tex]\(\frac{\pi}{2}\)[/tex]: Check if [tex]\(\sin\left(\frac{\pi}{2}\right) = 0\)[/tex]:
[tex]\[ \sin\left(\frac{\pi}{2}\right) = 1 \][/tex]
This is not true, so [tex]\(\frac{\pi}{2}\)[/tex] is not [tex]\(\sin^{-1}(0)\)[/tex].

3. [tex]\(\frac{3\pi}{2}\)[/tex]: Check if [tex]\(\sin\left(\frac{3\pi}{2}\right) = 0\)[/tex]:
[tex]\[ \sin\left(\frac{3\pi}{2}\right) = -1 \][/tex]
This is not true, so [tex]\(\frac{3\pi}{2}\)[/tex] is not [tex]\(\sin^{-1}(0)\)[/tex].

4. [tex]\(\frac{5\pi}{2}\)[/tex]: Check if [tex]\(\sin\left(\frac{5\pi}{2}\right) = 0\)[/tex]:
[tex]\[ \sin\left(\frac{5\pi}{2}\right) = 1 \][/tex]
This is not true, so [tex]\(\frac{5\pi}{2}\)[/tex] is not [tex]\(\sin^{-1}(0)\)[/tex].

Since the only angle that satisfies [tex]\(\sin(\theta) = 0\)[/tex] among the given choices is [tex]\(0\)[/tex], we conclude that:

[tex]\[ \sin^{-1}(0) = 0 \text{ radians} \][/tex]

Therefore, the answer is:
[tex]\[ \boxed{0} \][/tex]
