There are four types of relations as follows:There are four types of relations as follows: (i) one - one (ii) many - one (iii) one - many (iv) many - m..
Plot Linear equations in two variables
Summary Linear equations in two variables - An equation is called a Linear equation in one variable or an equation of degree one in one variable, if only a single variable with degree one occurs in the equation. An equation is called a Linear equation in ..
Following are the types of Functions:
(1) One-one function (2) Many-one function (3) Onto function (4) Into function Let the relation be from set A to set ..
Summary
An ordered pair has a pair of elements which occur in a definite order. The four types of relation are: one-one, many-one, one-many and many-man..
Summary
A linear equation of the form ax + by + c = 0 where a = 0, b 0 is called a linear equation in two variables. An equation is called a linear equation in one variable or an equation of degree one in one variable, if only a single variable with degree oneh..
Function Summary
Summary - A function is a relation on A x B is which A function is a relation on A x B is which (i) no two second elements have a common first element. (ii) every first element has a corresponding second element. Every function is either one-one onto or one-one into or many-..

Linear equations in two variables
A Linear equation is a first degree algebraic expression with one,two or more variables equated to a constant. Graphically a linear equation with one or two variables is a straight line whereas one with three variable represents a plane. A simple linear ..
(iv) many - many
For one element of A there is more than one corresponding element of B and for one element of B there is more than one corresponding element of A. The relation is called 'onto' if every element of B has a corresponding element of A. For example, Figures (i..

Tutor is the BEST. I have learned a lot from her. I never thought algebra will become my favourate subject. All because of Tutor Vista.
This Tutor Vista is GREAT! loved this session, it helped me heaps.
Tutor Vista tutor helped me understand and gave me some practices and showed me how to do them.
Tutor are so organized and neat with their teachings. She set up everything that made the problems more understandable by showing them in such a simple manner, I feel I could really learn from them and pertain it to my class! :)
