## What is Position Time Graph?

This article is about the position-time graph. Before going further details of the topic let us first understand how to draw these graphs. To draw graphs in x-y- plane Independent variable is always taken on the x-axis. We plot the dependent variable on the y-axis. The dependent variable is dependent on the independent variable through some function. Know more about Functions in Maths Let us … Continue reading What is Position Time Graph? »

## how to find the range of a function algebraically

For a function f:A ->B Set A is called the domain of the function f Set B is the called the co-domain of the function Set of Images of all elements in Set A is called the range i.e it is the set of values of f(x) which we get for each and every x in the domain Now lets see how to find the … Continue reading how to find the range of a function algebraically »

## common difference of arithmetic progression or sequence

Common difference of arithmetic progression or sequence is defined as the difference between the two consecutive terms in the arithmetic progression or sequence or series.  It is constant across the whole series if $a_1$,$a_2$ ,$a_3$.$a_4$ …..  are in arithmetic progression or sequence then $d=a_2 -a_1 = a_3 -a_2 =a_4 -a_3$…. If the common difference is not same across the series ,then series is not in … Continue reading common difference of arithmetic progression or sequence »
