CalculusFebruary 17th Fact-of-the-DayCalculus is fundamentally a study of rates of change, but extends to much more. Rate of change information makes it possible to answer questions like these: How much does VSWR change when antenna height is changed? How much does VSWR change when antenna length is changed? How much does VSWR change when antenna element spacing is changed? How much does amplifier plate current change when amplifier load-impedance changes. How much does amplifier output change when amplifier input changes? Problems like those can be solved by calculating the derivative, which also makes it possible to answer the often-important question, what is the lowest or highest value? The process can be reversed to calculate an integral. Integrals can be used to calculate areas, volumes, arc lengths, and other quantities. ©2005 Tigertek, Inc. All rights reserved.
