The traditional analog function generator with its customary triple-threat ensemble of square, triangle, and sine waveform outputs is a familiar tool on electronics lab benches. It’s also a classical ...

Swept sine waves are useful when you want to test a product over a wide frequency range. A large research project included the requirement to determine wave propagation in the open ocean. This ...

A signalling network known as the mitotic exit network (MEN) in S. cerevisiae and the septation initiation network (SIN) in S. pombe, although conserved, seem to regulate different cell-cycle ...

G. T. F. de Abreu, Arbitrarily tight upper and lower bounds on the Gaussian q-function and related functions, 2009 IEEE International Conference on Communications (ICC 2009), Vols 1-8, 1944–1949, ...

Solve the equation \(4\sin x^\circ - 3 = 0\), where \(0 \le x \textless 360\). From the graph of the function, we can see that we should be expecting 2 solutions: 1 solution between \(0^\circ\) and ...

In the paper, the authors find series expansions and identities for positive integer powers of inverse (hyperbolic) sine and tangent, for composite of incomplete gamma function with inverse hyperbolic ...

Many students think they've solved a trig equation when they get one answer (one size of angle \(x^\circ\)). However there's often more than one answer expected so be aware of this. Let's remind ...
