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
Functions Chapter in mathematics is quite important for JEE Preparation. Fundamentals of this chapter is required to clear to move ahead.I am trying to give few Important Solved Functions problems for JEE Maths in this article . You can refer below link for below for the detailed study material on Relations and Function Relation and function Study material So Here we go.I hope you will like … Continue reading Important Solved Functions problems for JEE Maths
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
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.
In this post we’ll lern Vector algebra in component form.
Component of any vector is the projection of that vector along the three coordinate axis X, Y, Z.
In component form addition of two vectors is
Here in this post we will go through a quick recap of vector algebra keeping in mind that reader already had detail knowledge and problem solving skills related to the topic being discussed. Here we are briefing Vector Algebra because concepts of electrostatics , electromagnetism and many more physical phenomenon can best be conveniently expressed using this tool.
