Math Problem Statement

Using the graph of y = sin(x), list all values on the interval [-8π/3, 3π/2] that satisfy the ordered pair (x, -√3/2).

Solution

The problem shown in your image is asking for the values of xx within a specific interval that satisfy the equation:

sin(x)=32\sin(x) = -\frac{\sqrt{3}}{2}

You are instructed to find the values of xx on the interval:

[8π3,3π2]\left[ -\frac{8\pi}{3}, \frac{3\pi}{2} \right]

Step-by-Step Approach:

  1. Identify the general solutions for sin(x)=32\sin(x) = -\frac{\sqrt{3}}{2}:

    • The sine function equals 32-\frac{\sqrt{3}}{2} at the angles x=4π3+2nπx = \frac{4\pi}{3} + 2n\pi and x=5π3+2nπx = \frac{5\pi}{3} + 2n\pi, where nn is any integer.
  2. Restrict the solutions to the interval [8π3,3π2]\left[ -\frac{8\pi}{3}, \frac{3\pi}{2} \right]:

    • We need to find all xx values in this interval where sin(x)=32\sin(x) = -\frac{\sqrt{3}}{2}.
  3. Check for solutions in the interval [8π3,3π2]\left[ -\frac{8\pi}{3}, \frac{3\pi}{2} \right]:

    • For n=2,1,0,1n = -2, -1, 0, 1, substitute nn into the general solutions to check which values fall within the interval.

Let me calculate the exact values for you.

The values of xx that satisfy sin(x)=32\sin(x) = -\frac{\sqrt{3}}{2} within the interval [8π3,3π2]\left[ -\frac{8\pi}{3}, \frac{3\pi}{2} \right] are:

x=8π3,7π3,2π3,π3,4π3x = -\frac{8\pi}{3}, -\frac{7\pi}{3}, -\frac{2\pi}{3}, -\frac{\pi}{3}, \frac{4\pi}{3}

These are the solutions you can use in your answer.

Would you like more details on any of the steps, or do you have any further questions?

Here are five related questions to deepen your understanding:

  1. What is the general form of solutions for trigonometric equations?
  2. How does the sine function behave over different quadrants in the unit circle?
  3. Why are there two general solutions for sin(x)=32\sin(x) = -\frac{\sqrt{3}}{2}?
  4. How do you determine which solutions fall within a specific interval?
  5. Can you find solutions to similar problems with other trigonometric functions like cos(x)\cos(x) or tan(x)\tan(x)?

Tip: Always visualize the unit circle to better understand where trigonometric values occur across different quadrants.
