Calculus, Radio Dials and the Straight-Line Frequency Variable Capacitor
Boyadzhiev, Khristo N.
International Journal of Mathematical Education in Science and Technology, v41 n5 p667-672 2010
Most often radio dials of analogue radios are not uniformly graded; the frequencies are cramped on the left side or on the right side. This makes tuning more difficult. Why are dials made this way? We shall see here that simple calculus can help understand this problem and solve it. (Contains 7 figures.)
