Allegro is claiming a record for its latest Hall-effect position sensor IC, describing it as “the smallest sine/cosine 3D sensor currently available in the market”. Called A33230, it comes in 3 x 2.9 ...

This circle has the centre at the origin and a radius of 1 unit. The point P can move around the circumference of the circle. At point P the \(x\)-coordinate is \(\cos{\theta}\) and the ...

A series of low-cost dc sine/cosine synchro or resolver converters can drive up to three torque receivers with accuracy within ±15 minutes of arc. Packaged on a 4.5- by 9.25-in. pc card,... A series ...

In high school, you probably learned that trigonometric functions – like sine, cosine and tangent –can be derived, geometrically, from a circle (hence why trig functions are also known as “circular” ...
