Electrical angle alignment of brushless dc (BLDC) motors is the process of determining how to apply electric current to the motor. In essence, it is determining where the magnets are with respect to ...

With Halloween upon us I thought it would be fun to tell you about a fact noticed by Steve Wang more than 20 years ago and published in the Journal of Recreational Mathematics (pdf of the paper here).

It may be necessary to use Pythagoras' theorem and trigonometry to solve a problem. The trigonometric ratios can be used to solve 3-dimensional problems which involve ...

Trigonometric functions are often used in embedded systems. Motor drivecontrol applications such as the Park Transform, Clarke Transform, andPWMgeneration use trigonometric functions extensively.

The class Trigonometry: Sine, Cosine, and Tangent discusses the three basic ratios that are the basis for trigonometry. Trigonometry is based on the specific relationships between the sides and angles ...

One of the more impotent features of the roughing hob for milling roughing straight-sided splines is the angle of the trapezia of the teeth of this hob. We can produce the trapezia easily on the ...

A small clay tablet that is 3,700 years old may be about to make studying trigonometry much easier, thanks to the work of an Australian mathematician. Babylonians approach to calculating triangles ...

Excel has built-in functions for sine and cosine, the two core trigonometric functions, and for hyperbolic sine and hyperbolic cosine, their hyperbolic counterparts. It also has built-in functions for ...
