The trigonometric ratios sine, cosine and tangent are used to calculate angles and sides in right angled triangles. We are now going to extend trigonometry beyond right angled triangles and use it ...

Sine, cosine and tangent all have different positive or negative values depending on what quadrant they are in. Calculating the area of a triangle using trigonometry Trigonometry can be used to ...

Mathematicians once turned up their noses at imaginary numbers. But complex analysis actually simplifies math and physics.

The app can also solve equations that use more complex formulas, such as the trigonometric functions of sine, cosine and tangent. You need to include the equals sign (=) at the end of each ...

His latest post doesn’t disappoint and shows how he uses the CORDIC algorithm to generate very precise sine and cosine waves in VHDL. CORDIC (Coordinate Rotation Digital Computer; sometimes ...
