## Matrix Multiplication

A matrix can be defined as an array of numbers, expressions that are arranged in rows and columns. A matrix is written in brackets [ ]. The order of matrix is defined as the number of rows * columns in a matrix. Consider a matrix given below The above matrix is of the order , [â€¦]

## Conversion Of Units

Length and Mass conversion Mensuration is an ancient concept. Every physical quantity like length, mass, time, temperature etc, have a specific unit. By definition, a unit is a magnitude of a physical quantity. There are two systems of units: SI units (International System of Units) Metric system For example, SI unit of length is a [â€¦]

## Co-ordinate Geometry

Coordinate Geometry is considered to be one of the interesting concepts of Mathematics. Coordinate Geometry describes the link between geometry and algebra through graphs involving curves and lines. It provides geometric aspects in Algebra and enables to solve geometric problems. It is a part of geometry where the position of points on the plane is [â€¦]

## Cube & Cuboid â€“ Total Surf…

In everyday life, objects like a wooden box, a matchbox, a tea packet, a chalk box, a dice, a book etc are encountered. All these objects have a similar shape. In fact, all these objects are made of six rectangular planes. The shape of these objects is a cuboid.   Cuboid: A cuboid is [â€¦]

## Differential Equations PDF

A differential equation can simply be termed as an equation with a function and one or more of its derivatives. You can read more about it from the differential equations PDF below. The functions usually represent physical quantities. The simplest ways to calculate quantities is by using differential equations formulas. Differential Equations are used to [â€¦]

## Statistics PDF

If we talk about statistics, it is a very broad subject and it has applications in a vast number of different fields. However, to give a gist about what statistics is, it is nothing but the methodology for collecting, interpreting, analysing, and formulating conclusions from the gathered information. In todayâ€™s scenario, scientists and mathematicians use [â€¦]

## Ratio and Proportion PDF

Ratio and Proportion are mathematical entities that help in comparison of numbers. In other words a ratio can be defined as a relationship between two numbers that helps in defining the quantity of the first number with the second number. You can learn more about it by downloading the Ratio and Proportion PDF below. In [â€¦]

## Area Of A Kite

Rhombus- A rhombus is a quadrilateral in which all the four sides are of equal length. Unlike square, none of the interior angle of a rhombus are not in measure. Kite- A quadrilateral figure having two pairs of equal adjacent sides, symmetrical only about one diagonal. The diagonals of a kite are perpendicular. Area of [â€¦]

## Compound Interest

What is Compound Interest? When we observe our bank statements, we generally notice that some interest is credited to our account every year. This interest varies with each year for the same principal amount. We can see that interest increases for successive years. Hence, we can conclude that the interest charged by the bank is [â€¦]

## Geometric Progression And Sum Of GP

Geometric progression â€“ Introduction: In an A.P, the difference between term and term will be a constant which is known as the common difference of the A.P. An Arithmetic Progression is in the form, Now, what if the ratio of term to term in a sequence is a constant? For example, consider the following sequence, [â€¦]
