Before we discuss on different quadrilaterals like the Rhombus, this is necessary to understand first what a quadrilateral is? This is a polygon with four sides, four vertices, and the four angles. The sum of its interior angle would 360-degree. A quadrilateral in simple terms has four sides of different length and angles of different […]

Surface area of a cone formula A cone is a popular geometrical shape with a flat surface that tapers to appoint on another side. Cone can be of different types but we will focus on right circular cone throughout this article. This is the cone with a flat surface tapers to appoint that is angled […]

The simple version of the quadratic formula was used 2000 years back by Babylonian mathematicians. The equation was almost the same as we are using today and it was written by a Hindu mathematician named Brahmagupta. This was only the quadratic equation that defined the concept of imaginary numbers and how can you show the […]

Surface Area of a Cylinder Formula A cylinder is a 3-dimensional structure with a circular base. It can also be taken as the set of circular disks which are stacked together one by one. Now take an example, where you are interested in painting the cylinder faces within the container. So, what you need to […]

What is Matrix? A matrix is a popular term in mathematics that is defined as the array of functions or numbers. Each matrix has two dimensions in the form of rows and columns. The number of rows is shown with the alphabet m and the number of columns is shown through the alphabet n. There […]

What is Factorial? The concept of Factorials was given in Algebra and further, they can be used for statistics, permutation, combinations, and to calculate the probabilities. Wherever you see the exclamation symbol(!) behind an integer, this is a factorial. Factorial Formula The Factorial formula is generally defined as the product of given number with all […]

What is Square? Square is the regular quadrilateral where all four sides are equal and angles are also same i.e. 90-degree each. This is a special type of rectangle where adjacent sides are equal. The square is a special rhombus where all four sides are equal and opposite angles are equal. This is a parallelogram […]

Root Mean Square Formula Root mean square is the square root of a mean square or it can be defined as the arithmetic mean of squares of group values. This is a special case of quadratic mean whose exponent value is two. Root mean square is also taken as the variable function based on the […]

What is Compound Interest? Compound interest is calculated on the principal amount and this is the interest that is accumulated over time. Unlike simple interest where instead of adding value to the principal amount, interest is calculated for next few years. The major application of compound interest can be seen in our daily transactions and […]
