An Introduction to mathematical Logic


This is most simple topic in the entire syllabus of mathematics and carries around 6 marks in HSC board exam.  Just understanding the tricks and doing ample practice you can score maximum marks.


More over due to Zero Calculation you can save lot of valuable time during the board exam. These time can be used to solve more time consuming problem.
According to new pattern of question paper there is no external option. So you cannot skip any topic. You have attempt each and every questions in board exam.
mathematical Logic

This topic is best for the students who are poor in trigonometry and calculus.
The score in exam.  not only depends upon how you work hard thought the year but also depends upon what you write in the answer paper during exam.
So friends we shall begin to learn Logic step by step.
What is included in this chapter?
1.Statement in logic.
2.Types of connectives and compound
    statements.
3.Truth tables of Conjunction and disjunction,
4. Truth tables of   negation, implication and double implication.
5. Converse, inverse and contrapositive of an implication.
6.Tautology, Contradiction, Contingency
7. Logical   equivalence and duals of a statement.
8.Negation of compound statement.
9.Quantifiers and quantified statements and their
   negations.
10.Application of logic to switching circuits.

In march 2019 board question paper there is a question no. 7 in section -B carries mark 2 and question no. 21 in section D carries mark 4.
Be touch with me.  I will give you tips and trick how to prepare for both board exams and JEE main exam.  If you like my video, please subscribe, like and share and comment my channel so I shall get inspiration to share my knowledge to you.  Thanking you for watching my video.

Application of logic to the switching circuit part-2

Image
In this post we are going to see two types of examples on the application of logic to the switching circuits.   A) how to express the given circuit in symbolic form of logic and B) how to construct the switching circuits if the logical statements are given.   So let’s begin. Ex. A) Express the following circuits in symbolic form of logic. In the circuit there are one S1 switch, two S2’ switches, one S3 switch and one S3’ switch. Let p: the switch S1 is closed.             ~q: the switch S2’ is closed.              r: the switch S3 is closed.          \  ~r: the switch S3’ is closed. The switch S2’ and S3 are connected in parallel and they are connected in series with the switch S1. Its symbolic form is p & (~q v r) . The switches S2’ and S3’ are connected in series. Its symbolic form  is ~q ~r . These branches are connected in parallel.  Hence given circuit in symbolic form is [p (~q v r)]v( ~q ~r ) 2)  In the circuit there

Hello friends I am Anil Kore I will explain you how to score more than 60 marks with little study and with simple and selected topics in Mathematics for HSC Board Exam. This post is only for the students who are weak in mathematics or find difficulties in studying mathematics or they came from rural areas and also students from poor families. These videos may help you to build a confidence to face HSC board exam. And score more than 60 marks. There are certain chapters which do not required strong background of algebra and trigonometry an. By preparing these chapters an ordinary student can score more than 60 marks in board exam. So we begin from 1 st Section in this post and 2 nd Section in my next post. SECTION 1 1.  Mathematical logic . It is most simple and student friendly. Free from need of algebra or trigonometry. You have to memorize 1. Truth Table of implication  2. Converse, Inverse and Contrapositive of    an implication. 2. Matrices same as lo

Converse, Inverse and contrapositive of an implication

Hello friends, Welcome to my blog mathstips4u. In my last post we have seen logical equivalence and some of their examples. In this post we are going to learn converse , inverse and contrapositive of an implication and some of their examples. If p → q is an implication, then there arises following three implications 1.      q → p is called converse of p → q 2.        ~ p →    ~q is called inverse of p → q 3.         ~ q →    ~ p is called contrapositive of p → q We shall see the truth table of converse , inverse and contrapositive of an implication. p q ~ p ~ q p → q conditional q → p converse ~ p →~q inverse ~ q → ~ p contrapositive T T F F T T T T T F F T F T T F F T T F T F F T F F T T T T T T 1 2 3 4 5
