    Antiderivative of 1.4x*cos(x^1.9)

    Your doing the math lab arn't you? I have the same problem except my f'(x) = 1.7x*sin(x^1.8)

    What Is the Correct Frequency of the Tuning Fork Based on Standing Waves?

    I am doing the same problem as well. So from what I have read, since the frequency of the tubes does not change, the wavelength of the standing wave would be 56.7-42.5=14.2cm or 0.142m. Then I would take the speed of sound divided by the wavelength to get the frequency, am I correct? Also, is...

    What is the length of the vibrating section of the violin string?

    Sorry for the late reply, the way I approached the question was correct. My answer was incorrect because the linear mass density in the question was in g/m while I needed to convert to kg/m. This question took me hours to figure out, I was sure the way I was doing was correct. For future...

    What is the length of the vibrating section of the violin string?

    I still don't quite get what the "vibrating section" of the violin string is. Are you saying that it is the length of the string; which makes no sense. I think the harmonic for stringed instruments is one or m = 1. Somewhere in between I have to use this formula: f1 =...

    What is the length of the vibrating section of the violin string?

    Homework Statement A particularly beautiful note reaching your ear from a rare Stradivarius violin has a wavelength of 39.1 cm. The room is slightly warm, so the speed of sound is 344 m/s. If the string's linear density is 0.620 g/m and the tension is 160 N, how long is the vibrating section...

    Index of refraction and oil/water

    Isn't it just lamda(c) = 2nd/m, m=1 for thinnest therefore d = 312.5nm
