An exterior angle of a triangle is equal to the sum of the two non-adjacent interior angles. This theorem provides another ...

The sides of right-angled triangles are labelled opposite, hypotenuse and adjacent. Trigonometry explores the relationship between sides and angles in right-angled triangles. The hypotenuse is the ...

As the numbers are known on the opposite and the hypotenuse, then we look for the ratio which uses both these sides (SOH CAH TOA). That ratio is the sine ratio. \(\sin (x^\circ ) = ...

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 ...

Japan’s National Institute for Materials Science (NIMS) and the Tokyo University of Science have created a solid-state electric double layer neuromorphic transistor, claiming it to be the fastest yet, ...

This article is part of the Ideas for Design Series: Vol. 3, No. 7. This simple, robust, and low-cost signal generator, based on the LM386 power amplifier IC, provides a trio of audio-band signals ...
