Sinusoidal Curve ```Name: elisabeth Status: N/A Age: N/A Location: N/A Country: N/A Date: N/A ``` Question: What is a sinusoidal curve? What is a physical example of something that would produce this curve? Replies: A sinusoidal curve is the graph of the sine function in trigonometry. A physical example is as follows: Set a pen on the bob of a pendulum that is quite long. Make sure the pen just touches paper just below it. Start the pendulum with a gentle, small motion. Pull the paper horizontally at a constant velocity under the paper. The path drawn is a sinusoidal curve. This can be done in a similar method with a tuning fork, but is more difficult to set up. ---Nathan A. Unterman Click here to return to the Mathematics Archives
