Ratio and proportion

thumb_ratio and proportion

A ratio defines how many times is one quantity with respect to another of same type. It is expressed as a minimized fraction and its numerator is called antecedent and denominator consequent. In practice these terms are not very important...

Basic and rich Trigonometry concepts and its applications

thumb_trigonometry basic and rich concepts

Trigonometry first established relationships between the angle and side measurements of a right angled triangle by defining trigonometric functions and thus extended the reach of mathematics wonderfully. At first look we may not find much application of trigonometry in real world, but one must consider, the modern civilization is based on the sinusoidal frequencies that are nothing but trigonometric functions...

Geometry basic concepts Part 2, Quadrilaterals Polygons Squares

thumb_geometry basic concepts 2

A quadrilateral is a closed shape on a plane bounded by four straight lines. To convey the concept of 'many' the word 'polygon' is used. A closed shape on a plane with many sides is a polygon. Though any number and types of polygons are possible, apart from triangles, we are generally interested in the polygons with four sides, the quadrilateral, the parallelogram, the rectangle, the rhombus and the square...
