Math Problem Statement

Y= sinx -6

Solution

The equation y=sin(x)6y = \sin(x) - 6 represents a vertically shifted sine function. Here's a breakdown of its components:

Key Features of y=sin(x)6y = \sin(x) - 6:

  1. Amplitude: The amplitude of the sine wave is 1, as the coefficient of sin(x)\sin(x) is 1.
  2. Period: The period of the sine wave is 2π2\pi, as the period of sin(x)\sin(x) is unchanged (2π1=2π\frac{2\pi}{1} = 2\pi).
  3. Vertical Shift: The graph of sin(x)\sin(x) is shifted downward by 6 units. This means the midline of the sine wave is now at y=6y = -6, instead of y=0y = 0.
  4. Range: The sine function sin(x)\sin(x) has a range of [1,1][-1, 1]. After the shift, the range becomes [7,5][-7, -5].
  5. Graph Behavior:
    • Peaks occur at y=5y = -5 (when sin(x)=1\sin(x) = 1).
    • Troughs occur at y=7y = -7 (when sin(x)=1\sin(x) = -1).

Follow-up Questions:

  1. What are the critical points of y=sin(x)6y = \sin(x) - 6 in a specific interval?
  2. How does the derivative of y=sin(x)6y = \sin(x) - 6 describe the function's slope?
  3. What are the solutions to sin(x)6=0\sin(x) - 6 = 0?
  4. How would adding a coefficient, like y=2sin(x)6y = 2\sin(x) - 6, affect the graph?
  5. How does the phase shift affect y=sin(x)6y = \sin(x) - 6 if we modify it to y=sin(xπ/2)6y = \sin(x - \pi/2) - 6?

Tip: A vertical shift changes the baseline of the function, but does not affect its periodicity or amplitude.
