In this article, we would learn about charge density and its formulas and would also solve some problems related to this concept. We encounter electric charge density while calculating electric field from various continuous charge distributions like linear, surface and volume. We also need the concept of charge density while studying current electricity. What is Charge Density?

How to tame Mathematics
Mathematics is a important subjects. Some student are good at it but some student find it difficult to break it.
It is also the most scoring subject.So getting good marks in this examination is imperative for the good percentage.
Here I will try to explain few tips to tame the Mathematics
1) There is very less theory in Maths.So we have less reading in it. Maths is learned by doing it.So Whenever you start with any maths chapter,pick up your pen and copy and starting practicing.You should not mug any therom.You show understand the theorem and solve it with paper and pen. If you know the proof of the theorem, you can solve the problems easily.

A relation is a function if no pair of the relation has the same first elements. On the graph,two points will lie in the same vertical line if and only if the first coordinate of the two points are same. Therefore if a vertical line intesect the Relation graph at two points then it is not a function. This is called the Vertical line test. If all vertical lines intersect a curve at most once then the curve represents a function

Complex numbers are the numbers of the form a+ib where a and b are real numbers.
Definition:- Complex numbers are defined as an ordered pair of real numbers like (x,y) where
z=(x,y)=x+iy
and both x and y are real numbers and x is known as real part of complex number and y is known as imaginary part of the complex number.
