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 […]

## 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 not simple interest. This […]

## Geometric Progression And Sum Of GP

Geometric progression – 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, […]

## Co – Prime Numbers

What are numbers? Try recalling the different types of numbers that you have come across, natural numbers, whole numbers, integers, even numbers, odd numbers, prime numbers, composite numbers etc. Prime numbers are those numbers which have only 1 and the number itself as its factors. What are co- prime numbers? Is it same as prime […]

## Area Of Rectangle

What is Rectangle? A rectangle is a four sided polygon having the length of the opposite sides to be equal. It can also be described or termed as an equiangular quadrilateral since all of its angles are equal (360°/4 = 90°). It can also be defined as a parallelogram containing opposite sides equal and parallel […]

## Calculus

Calculus is all about the comparison of quantities which vary in one-liner way. It has significant applications in Science and Engineering. Many of the topics that we study like velocity, acceleration or current in a circuit do not behave in a linear fashion. If quantities are changing continually, we need calculus to study about it. […]

## Area Of Quadrilateral

You are already acquainted with the term area. It is defined as the region occupied inside the boundary of a flat object or figure. The measurement is done in square units with the standard unit being square metres (m2). For the computation of area, there are pre-defined formulas for squares, rectangles, circle, triangles, general quadrilaterals […]

## Complex Numbers

While solving the equation of the form , the roots of the equations can take three forms which are as follows: Two Distinct Real roots Similar Root No Real roots (Complex Roots) The introduction of complex numbers in the 16th century made it possible to solve the equation . The roots of the equation are […]

## Quadratic Equation

We have already discussed about Polynomial in Algebra. A polynomial equation having degree of two is known as Quadratic equation. “Quad” means four but there Quadratic means ‘to make square.’ Standard form of Quadratic equation: The standard form of Quadratic equation is Where, x is an unknown and a,b,c are the constants such that If […]
