trigonometric ratios of special angles


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

In this post I am going to tell you some trick to remember trigonometric ratios of special angles. 
Special angles are  

These are most confusing formulas and also difficult to memorize.
I shall tell you a simple trick to remember trigonometric ratios of special angles.
 We  draw a following table for sin, cos and for tan



trigonometric ratios of special angles



Writing numbers 0,1,2,3 and 4 ascending order.
Dividing each number by 4. Taking square root of each.

In this way we have seen how to remember trigonometric ratios of special angles.
In my next post we will learn how to remember trigonometric ratios of quadrant-ale angles.

Mathematics for 12th class: part 1

Image
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. Ma...

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...

Converse, Inverse and contrapositive of an implication

Image
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 ...
