Easiest way to remember trigonometric formula

Hello friends, I am Anil Kore welcome to my blog mathstips4u.

In this post I am going to tell you some trick to remember trigonometric formula. 
Trigonometry is one of fundamental topic which start from secondary school.   What where it is hard you cannot skip these chapters because all other chapters like Limit, Derivative, Integration and some chapters from Physics depend upon trigonometry. If you gain mastery it will be easier to prepare other topics based on trigonometry.
Being a student of mathematics you should make a friendship with trigonometry. The toughest part of trigonometry that student face is to remember its formulas.
In this video I will give you an easiest method to remember some of the important trigonometric formula. Following are the formulas you have to be by heart or you have to do lot of exercise from your text book to remember these formulas.

There are some tricks to remember these formulas but that even increases complexity. So you have to by heart these formulas.  
In my next post we will learn how to remember trigonometric ratios of special angles.

Double implication or biconditional

Image
Hello friends, Welcome to my blog mathstips4u. In my last post we have seen implication and its truth table and some of its examples. Some of important examples I intentionally left as exercise. The solution of these examples is provided at the end of this post.  We shall start with Bi-conditional or double implication ( ↔ ) : Let p and q be two simple statements. Then the compound statement ‘p if and only if q’ is called the bi-conditional or double implication, denoted by p ↔q or p = ＞ q . It is read as p implies and implied by q. p ↔q is defined to have the truth value ‘true’ if p and q both have the same truth values. Otherwise   p ↔q is defined to have the truth value ‘false’. Truth table of bi-conditional p ↔q p q p ↔q T T T T F F F T F F f T Note: 1. p ↔q, q ↔p both are same. 2. p ↔q is the conjunction of a conditional and its converse i.e. p → q and ...

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 ...

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...
