Math Problem Statement
Solution
To analyze the graph and fill in the table, we need to extract the key properties of the waveform shown. I'll start by identifying the following components:
- Amplitude: The maximum vertical distance from the centerline (axis) of the wave to its peak.
- Period: The horizontal distance between two consecutive peaks (or troughs) of the wave.
- Frequency: The reciprocal of the period, representing how many cycles occur in a given interval.
- Wave's Axis: The horizontal line around which the wave oscillates, typically at unless shifted vertically.
- Phase Shift: The horizontal shift of the wave compared to a standard sine or cosine wave.
Let me now analyze the waveform and fill out the requested table.
-
Amplitude: The graph oscillates between approximately and , so the amplitude is .
-
Period: The graph completes one full cycle between and . Therefore, the period is .
-
Frequency: Since frequency is the reciprocal of the period, the frequency is .
-
Wave's Axis: The wave oscillates about , which means the wave's axis is at .
-
Phase Shift: Comparing this to a standard cosine curve, which typically starts at its maximum at , this wave starts at , indicating a phase shift of unit to the right.
Now, let me place this information into the table:
Curve Type | Amplitude | Period | Frequency | Wave's Axis | Phase Shift (k) |
---|---|---|---|---|---|
Cosine Curve | 2 | 2 | 0.5 | 3 | 1 |
Sine Curve | - | - | - | - | - |
(Note: Since the waveform looks like a shifted cosine wave, there is no need to fill in the sine curve details unless specifically asked.)
Would you like further clarification on any of these properties or the table?
Here are five related questions to expand on this topic:
- How would the graph change if the amplitude were increased to 3?
- What effect does doubling the frequency have on the period of the wave?
- How can you identify a sine curve from a cosine curve based solely on their phase shifts?
- How does a vertical shift affect the wave’s axis and overall graph?
- How would the graph be affected if the phase shift were negative?
Tip: Always remember that the amplitude controls the wave's height, the period affects its width, and the phase shift moves the wave horizontally.
