Math Problem Statement

arcsin1/√3

Solution

The value of arcsin(13)\arcsin\left(\frac{1}{\sqrt{3}}\right) represents the angle θ\theta such that sin(θ)=13\sin(\theta) = \frac{1}{\sqrt{3}}. Let's solve this step by step:

Step 1: Understanding the range of arcsin\arcsin

The arcsin(x)\arcsin(x) function gives the angle in the range π2θπ2-\frac{\pi}{2} \leq \theta \leq \frac{\pi}{2}.

Step 2: Solve sin(θ)=13\sin(\theta) = \frac{1}{\sqrt{3}}

We know sin(θ)=oppositehypotenuse\sin(\theta) = \frac{\text{opposite}}{\text{hypotenuse}}. If sin(θ)=13\sin(\theta) = \frac{1}{\sqrt{3}}, this corresponds to the angle where such a ratio occurs.

The exact value of this angle is arcsin(13)=π60.5236radians\arcsin\left(\frac{1}{\sqrt{3}}\right) = \frac{\pi}{6} \approx 0.5236 \, \text{radians}.

Final Answer:

arcsin(13)=π6\arcsin\left(\frac{1}{\sqrt{3}}\right) = \frac{\pi}{6}


Would you like further clarification or a detailed derivation? Here are some questions to consider:

  1. What are the properties of the arcsin\arcsin function?
  2. How does the sin\sin function relate to the unit circle?
  3. Can you express 13\frac{1}{\sqrt{3}} in terms of trigonometric values of common angles?
  4. How does the range of arcsin(x)\arcsin(x) affect solutions?
  5. What are the equivalent angles in degrees for π6\frac{\pi}{6}?

Tip: Memorizing the sine values of common angles like 30,45,30^\circ, 45^\circ, and 6060^\circ helps with quick calculations!
