Now Unit test 1 is complete.

We will be preparing for Unit Test 2 and the final exams.

In maths We shoud start with the construction.

We have to learn . Start learing from your text books a nd be a pandit.

a. To draw Incircle or circumcircle(This is important for 2014).

b. Indirect Tangent(Important for 20140).

The 2 things i.e. Define and Differentiate will help at least those students who are very weak. If they make preparation for these 2 topics they will easily pass. If a student is above average then it will add up in his merit and also will make clear conception.

So make a fresh coy and start writing all the definitions in a a single place and all the differences in single place and memorize it . It will help you a lot in your madhyamik preparation and will surely land you on the other side of fail i.e. pass.

All the define topic that has to be covered is displayed on the blog and differentiate also. 2 differences for each of the differences should be made clear in writing.

Yes , So we have got the materials ready for the first unit test.

In Physics , I will try to categorize all the questions in 4 categories .
-----------------------------------------------------------------------------
a. Define.

b. Difference.

c. Why 

d. How 

All students must remember these all 4 types of questions . One who wants to be the topper must go through all the 4 types of questions. If some body is not good in physics or do not have so much confidence then to pass he/she should prepare first 2 types.

The first two categories for the first unit test has been displayed on the blog. In the next article we will try to elaborate the last two types.

At first a student should try to remember the definitions which is the first step . A candidate should make fresh copy and start writing all the definitions written in the book. Start remembering at least 5 definitions per day and also the units after understanding.
---------------------------------------------------------------------------
In mathematics we should at first remember the formulas that is displayed on the blog.

Then we will directly prepare for the board exam.

We know that in the beginning we will be getting short type questions. For this we have to practice a lot of short type questions. The formula that will be used has been listed . Next comes 2 marks questions which is also short and concept based for which formula has been listed and will be modified.

Any suggestion/questions  for improvement can be sent to indraitip@gmail.com. I will try to solve to  at earliest.

Also after this post I am trying to take each topic and practice 10 questions daily in mathematics.

Daily questions which will start from concept based very easy to moderate and tougher.

The success mantra : Slow and steady wins the race.

Maths Formula For Revision

We all know that formula is the shortest way to  achieve any result. In Maths either you can go through the long way or you can have the process in your mind and the shortest way remembered in your mind and it should be on your tongue . Your mathematics skill will depend how much you have memorized the formula and how you can apply the formula in the fastest way. I have tried here to note down all the formulas , which will be required for a candidate who takes preparation for competitive exams.
It is not exhaustive and it will be modified daily or else once in a week.



1. (a+b)2=a2 +b2+2ab.                   =>   a2+b2 = (a+b)2-2ab
2. (a-b)2=a2+b2-2ab.                      =>   a2+b2 =  (a-b)2 + 2ab
3. a. (a+b)3=a3+b3+3a2b+3ab2.      =>   a3+b3 =   (a+b)3 - 3a2b -3ab2
    b. (a+b)3=a3+b3+3ab(a+b)         =>   a3+b3 =   (a+b)3 - 3ab(a+b)      
4. (a-b)3=a3-b3-3a2b+3ab2.            =>   a3 - b3 =   (a-b)3 + 3a2b -3ab2
    (a-b)3=a3-b3-3ab(a-b)                        =>      a3- b3 =   (a-b)3 + 3ab(a-b)       
5. a2-b2=(a+b)(a-b)
6. a. (a+b)2 + (a-b)2 = 2 (a2 + b2)
    b. (a+b)2 - (a-b)2 = 4ab
====================================

Mensuration - Formulae.

1. Area of a triangle    - sqrt ( s * (s-a) * (s-b *(s-c ) ) where * denotes multiplication.
                                      ( For scalene triangle )
                                    - (1/2 ) * base * height  (For right angled triangle.)
                                    - (a * sqrt(3))/4              (For equilateral  triangle.)

2. Area of Rectangle           – Length x Breadth .
3. Area of Square                -  (Side)2
     Diagonal of Square           - Sqrt(2) * a where a= side.
4. Area of Rhombus           - (1/2) x d1 x d2   where d1=diagonal1 and d2=diagonal2.
                                            - Base * Height
5. Area of Trapezium         - (1/2) x height x (sum of length of parallel sides )
6. Area of Parallelogram     - (1/2) x height x (sum of length of parallel sides )

7. Area of Circle                   - PI * r * r ( where PI=3.14 , r=radius )
    Circumference of circle    - 2 * PI * r
8. Area of Cuboid                -2*(l*b+b*h+l*h) , symbols have usual meanings.
9. Volume of Cuboid          -Length * Breadth * Height
10. Diagonal of Cuboid       -Sqrt(l*l + b*b + h*h ), where symbols have usual meanings.
=====================================================

   
More Coming Soon.......

Saturday, 4 May 2013

Today we shall learn about the  6 questions that are coming in objective category.

These are basically fundamental question which are taken from mainly all the chapters . For this we have to go through the concepts of each of the chapter and the theorem of geometry and their application.

What you have to revise in this are as follows.

1. Formula for algebra

2. Application of concepts in Arithmetic , Geometry, Mensuration etc.
--------------------------------------------------------------------------------------
We will list below the formula that will be useful here. List will be continued.
---------------------------------------------------------------------------------------
1. Profit = S.P - C.P

2. Loss = C.P  - S.P

3. Profit % = Profit
                    -------  X 100
                      C.P
4. Loss % = Loss
                    -------  X 100
                      C.P
5. S.I  = PxRxT
             --------- , P = Principal , R = Rate , T = Time
               100
6. Amount=P(1+r/100)^n , where A=Amount , P=Principal, r=Rate , n =time , in compound interest.

7. If a^2 + b^2 =0, then a=0 and b=0.

8. In geometry , We know that the sum of opposite angles of a cyclic quadrilateral is 180.

9. The sum of the adjacent angles are 180.

10. The external angle of a triangle is equal to the sum of the interior opposite angles.

11. If x<=a, then the maximum value of a will be  a.

12. To remember all trigonometric values of sine , cos, tan, cot, sec ,cosec of 0,30,45,60,90.

13. The angle subtended at the centre will be double that of the angle at the circumference in a circle.

14. The area of the triangle betweens the parallels is equal to the half of the area of the parallelogram.
