    Amplitude
In summary, the amplitude coefficient in front of the sin function is always positive, with a value of 1 in this case.

if f(x) = - sin(x/5 - p) are given, then the amplitude must be -1, correct??

Thread moved to homework help. Please take care to post homework and coursework type questions in the Homework Help forum section of the PF, and not in the general technical forums.

In answer to your question, yes, the amplitude coefficient in front of the sin function is A=-1.


(EDIT -- See farther down the thread where the magnitude of "amplitude" is discussed... my answer here is wrong)

But the quiz system marked me incorrect?? why??

yes, solve it, the amplitude is -1, but got the symbol ||, so it turns positive.

You were marked wrong because "amplitude" is always positive: here it is 1, not -1.
 

FAQ: What is the amplitude of -sin(x/5 - p)

1. What does the amplitude of a function represent?

The amplitude of a function represents the maximum distance between the function's graph and the x-axis. In other words, it is the highest point of the function's graph.

2. How is the amplitude of a function calculated?

In the case of a trigonometric function, such as -sin(x/5 - p), the amplitude can be calculated by taking the absolute value of the coefficient of the trigonometric term. In this case, the amplitude would be |-1| = 1.

3. What is the significance of the negative sign in front of the sin function?

The negative sign in front of the sin function indicates that the graph of the function will be reflected over the x-axis. This means that the highest point of the graph will become the lowest point, and vice versa.

4. How does the amplitude affect the graph of -sin(x/5 - p)?

The amplitude of a function determines the vertical stretch or compression of the graph. In the case of -sin(x/5 - p), the amplitude of 1 means that the graph will have a maximum height of 1 unit above and below the x-axis.

5. Can the amplitude of a function be greater than 1?

Yes, the amplitude of a function can be greater than 1. This would result in a graph that is more stretched out vertically. For example, if the amplitude of -sin(x/5 - p) was 2, the graph would have a maximum height of 2 units above and below the x-axis.
