Important Mathematical Formulas

  Maths Formulas

1. (a + b)(a – b) = a² – b²

1. (a + b + c)² = a² + b² + c² + 2(ab + bc + ca)

1. (a ± b)² = a² + b²± 2ab

1. (a + b + c + d)² = a² + b² + c² + d² + 2(ab + ac + ad + bc + bd + cd)

1. (a ± b)³ = a³ ± b³ ± 3ab(a ± b)

1. (a ± b)(a² + b² m ab) = a³ ± b³

1. (a + b + c)(a² + b² + c² -ab – bc – ca) = a³ + b³ + c³ – 3abc =
   
   1/2 (a + b + c)[(a - b)² + (b - c)² + (c - a)²]

1. when a + b + c = 0, a³ + b³ + c³ = 3abc

1. (x + a)(x + b) (x + c) = x³ + (a + b + c) x² + (ab + bc + ac)x + abc

1. (x – a)(x – b) (x – c) = x³ – (a + b + c) x² + (ab + bc + ac)x – abc

1. a⁴ + a²b² + b⁴ = (a² + ab + b²)( a² – ab + b²)

1. a⁴ + b⁴ = (a² – √2ab + b²)( a² + √2ab + b²)

1. aⁿ + bⁿ = (a + b) (a ^n-1 – a ^n-2 b + a ^n-3 b² – a ^n-4 b³ +…….. + b ^n-1)

(valid only if n is odd)

1. aⁿ – bⁿ = (a – b) (a ^n-1 + a ^n-2 b + a ^n-3 b² + a ^n-4 b³ +……… + b ^n-1)

{where n ϵ N)

1. (a ± b)²ⁿ is always positive while -(a ± b)²ⁿ is always negative, for any real values of a and b

1. (a – b)²ⁿ = (b – a)²” and (a – b)²ⁿ⁺¹ = – (b – a)²ⁿ⁺¹

1. if α and β are the roots of equation ax² + bx + c = 0, roots of cx” + bx + a = 0 are 1/α and 1/β.
   if α and β are the roots of equation ax² + bx + c = 0, roots of ax² – bx + c = 0 are -α and -β.

1. • n(n + l)(2n + 1) is always divisible by 6.
   
   
   
   • 3²ⁿ leaves remainder = 1 when divided by 8
   
   
   
   • n³ + (n + 1 )³ + (n + 2 )³ is always divisible by 9
   
   
   
   • 10^{2n + 1} + 1 is always divisible by 11
   
   
   
   • n(n²- 1) is always divisible by 6
   
   
   
   • n²+ n is always even
   
   
   
   • 2³ⁿ-1 is always divisible by 7
   
   
   
   • 15^2n-1 +l is always divisible by 16
   
   
   
   • n³ + 2n is always divisible by 3
   
   
   
   • 3⁴ⁿ – 4 ³ⁿ is always divisible by 17
   
   
   
   • n! + 1 is not divisible by any number between 2 and n
     
   (where n! = n (n – l)(n – 2)(n – 3)…….3.2.1)
   for eg 5! = 5.4.3.2.1 = 120 and similarly 10! = 10.9.8…….2.1= 3628800
   

1. Product of n consecutive numbers is always divisible by n!.

1. If n is a positive integer and p is a prime, then n^p – n is divisible by p.

1. |x| = x if x ≥ 0 and |x| = – x if x ≤ 0.

1. Minimum value of a².sec²Ɵ + b².cosec²Ɵ is (a + b)²; (0° < Ɵ < 90°)
   
   for eg. minimum value of 49 sec²Ɵ + 64.cosec²Ɵ is (7 + 8)² = 225.
2. among all shapes with the same perimeter a circle has the largest area.

1. if one diagonal of a quadrilateral bisects the other, then it also bisects the quadrilateral.

1. sum of all the angles of a convex quadrilateral = (n – 2)180°

1. number of diagonals in a convex quadrilateral = 0.5n(n – 3)

1. let P, Q are the midpoints of the nonparallel sides BC and AD of a trapezium ABCD.Then,
   ΔAPD = ΔCQB.

How To Score 90+ in Maths Board Exam

Maths is the subject which matters a lot for students as well as for the parents. All of us give the most importance to Mathematics , no matter we are good or bad at it!!

It's not really hard to get 90+ in maths exam as it's predefined about whats going to come in exam , and unlike other theoretical  subjects, we don't have to learn each question by heart. We just need to learn the concept behind the question and solve it in easily manner.


Steps to top this Math's board exam.

1. Almost every question in exam comes from NCERT, so never underestimate the value of NCERT book  i already have published " NCERT MATHEMATICS SOLUTIONS " which will help you a lot.

2. Check out Blueprint Of Mathematics Exam, this will give you an idea about the questions which would be there in exams.

                                                Indian Study Time presents Blue print mathematics class xii

3. If you are not prepared at all and few days are left. Than  don't try to learn new things. Just focus on the topics you already learned about. 

    Don't leave  12.2 exercise , there will be a question from it for 6             marks , Probability , don't go for differentiation hard questions.

 NCERT is the key!!! 

Just Do it 

Best Of Luck!!
