We measure the frequencies at which wires vibrate in cycles (trips back and forth) per sec. The unit of measure is a hertz: 1 cycle per sec. Middle A on a piano has a frequency 440 hertz. For any given wire, the fundamental frequency y is a function of four variables: r: the radius of the wire; l: the length; d: the density of the wire; T: the tension (force) holding the wire taut. With r and l in centimeters, d in grams per cubic centimeter, and T in dynes (it takes about 100,000 dynes to lift an apple), the fundamental frequency of the wire is y " $2 1 rl$#$p T d $$. If we keep all the variables fixed except one, then y can be alternatively thought of as four different functions of one variable, y!r", y!l", y!d", and y!T ". How would changing each variable affect the strings fundamental frequency? To find out, calculate y%!r", y%!l", y%!d", and y%!T ".
