Linear Inequations

Before we dive into the sums, it is necessary t understand all the terms related to this topic. For instance, many misunderstand the question because they fail to figure out the difference between an inequality and an inequation. What is an Inequality? The open sentence which involves >, ≥, <, ≤ sign are called an

Representation of linear inequalities

Linear inequalities refer to a relation that holds between two values when they are different. Before moving ahead let us clear some basic concepts:- If the notation a<b means that a is less than b. The notation a>b means that a is greater than b.  Notation a b  means that a is not equal to b

Trigonometry Functions

Trigonometry studies the relationships between the angles and sides of a triangle.Furthermore, it is used in many spheres of life from describing the state of an atom to analysing a musical note. So trigonometric functions are sine, cosine and tangent. Given below are the trigonometric ratios at a glance and their relation with the functions.

Bayes’ Theorem

Before beginning with Bayes’ Theorem let’s skim through the formula for Conditional Probability. The conditional probability of an event B is the probability that the event will occur given the knowledge that another event A has already occurred. This expression for probability is as P(B|A), notation for the probability of B given A. If events A and B are not independent, then the probability of the intersection of

CBSE announces “Know Your Aptitude” tests for Class 9, 10 students

CBSE has recently introduced a Know Your Aptitude Test. To learn what it is and how it will be helpful, read the post! Know Your Aptitude is an initiative by Central Board of Secondary Education. The exam primarily aims at allowing the students to asses the correct field for future-studies. It measures the child’s inclination

Triangles [Types and Properties]

The plane figure bounded by three lines, joining three non collinear points, is called a triangle. As per the number of sides and the measure of the angles of triangle, there can be various types of triangles as given in the figure below. Important Properties of a Triangle The sum of the three interior angles

Comparing Quantities [Percentage, Decimals and Fractions]

Comparison of various quantities, is an important concept of mathematics as well as very useful in daily lives. It is not much of a task when the quantities are either natural numbers or in the same format. However, while comparing terms of different forms, problem arises.  Comparison of quantities is generally done to see which

Determinants

What is a determinant? The determinant is a value that can be computed from the elements of a square matrix. The determinant of a matrix A is denoted by det(A), det A, or |A|. Determinant 1 × 1 : If A=[x] ,  det(A) = |A| =x  2 × 2 ( Second order ) : 3

Matrices

In mathematics, a matrix  is a rectangular array of numbers, symbols, or expressions, arranged in rows and columns. For example, the dimensions of the matrix below are 2 × 3 (read “two by three”), because there are two rows and three columns:         1. The order of a matrix is of the
