Excel has over 475 formulas in its Functions Library, from simple mathematics to very complex statistical, logical, and engineering tasks such as IF statements (one of our perennial favorite stories); ...

Most engineering labs have digital oscilloscopes, but many engineers don’t fully explore their features. Among the more interesting features of a digital oscilloscope is its math channel, which can ...

A rule for creating a "y" output from an "x" input. For example, the y value of the function f(x) = 15x is 30 if x is 2. THIS DEFINITION IS FOR PERSONAL USE ONLY. All other reproduction requires ...

Oscilloscope measurement parameters provide accurate measurements of acquired waveforms. Most digital oscilloscopes offer around twenty-five standard parameters like frequency, peak-to-peak amplitude, ...

THE object of the authors of this volume of mathematical tables is “to supply a comprehensive set of tables of the numerical values of the elementary functions which are in constant use in mathematics ...

Mathematicians used “magic functions” to prove that two highly symmetric lattices solve a myriad of problems in eight- and 24-dimensional space. The points could be an infinite collection of electrons ...
