LINEAR EQUATIONS

GO TO LINEAR EQUATIONS

LINEAR EQUATION
      A statement of equality which involves literals / variables is called equation.
      An equation in which the highest degree of the variable is one is called linear equation.
LINEAR EQUATION IN ONE VARIABLE
      If only one variable is involved, then it is called linear equation in one variable.
      An equation of the form ax+b=c, where a,b,c are numbers, a≠0 and ‘x’ is a variable
      
LINEAR EQUATION IN TWO VARIABLES

      A linear equation with two variables is called linear equation in two variable say x and y but the highest degree of each variable is one. Linear equation of the form ax+by+c=0 is called linear equation in two variables.

CORRELATION OF MATHEMATICS WITH OTHER SUBJECTS

Image
        Mathematics correlates with almost all school subject. Sciences uses mathematics the most. Even the Fine Arts use mathematics to some extent. Mathematics has characteristics like symmetry, similarity, originality, generalization and verification. All these characteristics make mathematics very usable, practical and versatile. Relation of mathematics with science, economics and fine arts is covered in this text Relation of Mathematics with Sciences       1. Physics  -           (i) The numerical derivations of many Laws of science are provided by mathematics.      (ii) Newton Laws of Motion, Gravitational Laws, Boyle's Law, Charles Law etc. require mathematics for practical understanding.          (iii)  All measurements, units and measuring devices depend upon mathematics.            2.  Chemistry -       ...

MATH PROBLEM SOLVING

SOLVING A PROBLEM OR PROBLEM SOLVING IN MATHEMATICS             I have a problem, I want to solve it. Say the problem is - Who Shaves the Barber?  To solve this, do I need mathematics? The answer is No. I just need to ask the barber and the problem will be solved. Lets take another example. I want to go on a vacation for 5 days. For that I have to take a leave, select a place for vacation, check how much money is required, check booking dates with hotel, decide mode of transport and make a time-plan of visits to different places during vacation. Now the question arises, "Do I need mathematics?" The answer is Yes. Money required, dates, distance to travel and time-plan need mathematics. This is the real life example of problem-solving in mathematics. For this you have to think, plan, reason out, apply logic and solve the problem systematically.              Writing solution and finding solution are two different scenar...

OBJECTIVES OF TEACHING MATHEMATICS

Image
INSTRUCTIONAL AND BEHAVIOURAL OBJECTIVES   Instructional Objectives  1. These are the statements of measurable learning that is intended to take place as a result of instruction. 2. These are set according to the level of students in a particular class. 3. These are classroom objectives unique to each course or subject. 4. These are derived from the terminal behaviour which the students are expected to display as a consequence receiving instruction. Behavioural Objectives 1. These are the objectives in terms of behaviour of the students. 2. These are description of observable student behaviour related to learning. 3. Behavioural objectives should identify the following    (i) Learner - for whom the objectives are written.     (ii) Behaviour - targeted for change.    (iii) Conditions - under which the behaviour will be performed.    (iv) Criteria - for the acceptable performance of behaviour to occur.   EXAMPLE TOPIC -...
