Introduction Rectangular Pyramid is a three-dimensional solid figure with a rectangular base and four triangular flat surfaces. There are many types of pyramids, such as the square pyramid, triangular pyramid, pentagonal pyramid, and hexagonal pyramid concerning the shapes of the base and the number of triangle surfaces. The surfaces of the pyramid are plane figures with straight lines, which can also be called polygons. If a solid figure is made up of polygons then it is called a polyhedron. Rectangular pyramids, or pyramids in general, are Polyhedrons. One of the common types of the pyramid is the rectangular pyramid. The ... Read More

Introduction Mathematical induction involves principles which are a specific technique to prove theorems and statements in algebra which are expressed in the form of n; where n belongs to natural numbers. In mathematical induction any statement is proved for n=1 and then for any variable. What is PMI? Mathematical Induction can be described as a tool to prove any statement A(n) which can hold for natural numbers n=1, 2, 3, 4, 5......n. Mathematical Induction is based on some principles called the principle of mathematical induction (PMI). In order to prove a result for a statement A(n), we can use the ... Read More

Introduction Even numbers are numbers in the form of n = 2k, which means the number which can be divided by 2. Mathematics is a branch of science that arose due to the needs of man for calculation in business, knowing the relationship between numbers, measuring the land, in predicting cosmic events. Mathematics is used as an important tool in many fields of the world such as natural sciences, engineering, medicine, finance, and social sciences. Applied mathematics deals with the use of mathematics in other fields to stimulate and apply new scientific discoveries. Mathematics is not only numbers and their ... Read More

Introduction A denominator is the number that appears below the horizontal line. In mathematics, a fraction is represented by a number that identifies a portion of a whole. A fraction is a component or section taken from a whole, which can be any number, a certain amount, or an object. The denominator is the fraction's divisor. In a fraction, the denominator is the number or integer that lies below the horizontal line. A fraction's numerator is above the line. If a denominator is equal to 0, the result is an indefinite value. In this tutorial, we will discuss the denominator, ... Read More

Introduction Pie charts look like a slice of pizza (or pie); hence the name given was pie chart. The Statistical Breviary by William Playfair, published in 1801, is largely credited with creating the first known pie chart. Pie charts are frequently utilised in the media and in the business world. But because studies have shown that it can be difficult to compare data inside a single pie chart or between various pie charts, many experts advise against using them. Most of the time, pie charts can be replaced by other plots, such as bar charts, box plots, dot plots, etc. ... Read More

Introduction A matrix that consists of several objects arrayed in a rectangular order. The word "matrix" is a plural matrix and is not commonly used to refer to a matrix. There are many types of matrices, which are basically categorized by element value, order, number of rows and columns, and so on. In this tutorial, we will discuss types of matrices. What is a Matrix? A matrix is an arrangement of numbers, variables, symbols, or expressions in a rectangular table that contains different numbers of rows and columns. These are rectangular arrays that define various operations such as addition, multiplication, ... Read More

Introduction The polar form of a complex number $\mathrm{z\:=\:x\:+\:iy\:is\:r(\cos\theta\:+\:i\:\sin\theta)}$.In mathematics, there are various coordinate systems to represent real numbers. However, the complex number system can be represented in two ways, i.e., rectangular and polar coordinate systems. In this tutorial, we will learn about complex numbers, their representation in polar form, and some basic formulae related to complex numbers with solved examples. Complex Number The complex number is a category of a number system associated imaginary numbers. In other words, complex numbers are the summation of real and imaginary numbers. The imaginary numbers are nothing but the square root of the ... Read More

Introduction PEMDAS means the order of operations for mathematical expressions involving more than one mathematical operations. In an arithmetic expression containing more than one mathematical operator or a parenthesis, there is a preference in order of operations to be followed to get the correct result of the arithmetic expression the order of operations in a shortcut called PEMDAS. The change in the order of operations would change the result of the arithmetic expression. Therefore, the PEMDAS rule is strictly followed to get the correct result. In the United Kingdom, it is called BODMAS, in Canada, it is called BEDMAS. In ... Read More

Introduction Ordinate is the second component in the ordered pair (x, y). There are two major branches of mathematics, including algebra and geometry. Both have separate uses and applications. However, the French mathematician Rene Descartes derived a concept through the combination of algebra and geometry. This concept helps us to express the location of any object, point, or line in the coordinate system. However, there are various topics included in the coordinate system. In this tutorial, we will learn about the coordinate system, the cartesian plane, its components (ordinate and abscissa), and some basic formulas with solved examples. Coordinate System ...

Introduction Operations on rational numbers such as basic operations like addition, subtraction, multiplication and division. Rational numbers are fractions containing a numerator and a denominator (the denominator should be a non-zero integer). In algebra, rational numbers are used in various science, mathematics, and economics sectors. Moreover, various operations such as addition, subtraction, division, and multiplication are necessary to obtain a third rational number. All these operations are quite different from the algebraic operations of integers. In this tutorial, we will discuss number systems, rational numbers, comparison between rational numbers, and their various operations with solved examples. Number System A number ... Read More
