A chord (i.e., the diameter of the circle) is considered special as it leads us to another important theorem in chord geometry. The center of a circle bisects the diameter. This property leads us to a theorem that states that a chord is always perpendicular to a radius that bisects th...
Euclidean geometry is the study of plane and solid figures on the basis of axioms and theorems employed by the ancient Greek mathematician Euclid. The term refers to the plane and solid geometry commonly taught in secondary school. Euclidean geometry is
This is essentially a table of sines, which can be seen bydenotingthe radiusr, the arcA, and the length of the subtended chordc, to obtainc= 2rsinA/2. Because Ptolemy used the Babylonian sexagesimalnumerals and numeral systems(base 60), he did his computations with a standard circle of...

The definition of a radian is the angle of an arc in a circle which is created by enclosing the radius of the circle around its circumference. We represent this angle between two lines through radians as well as degrees. The total angle of a circle equals 360\degree or we can call it ...
Albeit its simplicity, the concentric spheres head model is widely used in EEG. The reason behind this is its simple mathematical definition, which allows for the calculation of lead fields with negligible computational cost, for example, for iterative a
