Important Maths Formulas
(a ± b)2 = a2 ± 2ab + b2
(a + b + c)2 = a2 + b2 + c2 + 2(ab + bc + ca)
(a + b + c + d)2 = a2 + b2 + c2 + d2 + 2(ab + ac + ad + bc + bd + cd)
a2×a1 = a3
a2÷a1 = a1
(a2)1 = a2
a-2 / a2 = 1
(ab)2 = a2xb2 =ab4
a0 = 1
a1/2 = 2√a.
(√a)2 = a

Pythagoras's theorem
The Pythagorean theorem is also known as Pythagoras's theorem. if c denotes the length of the hypotenuse and a and b denote the lengths of the other two sides, the Pythagorean theorem can be expressed as the Pythagorean equation:
a2+b2=c2
If the length of both a and b are known, then c can be calculated as
c = √(a2+b2)
If the length of the hypotenuse c and of one side (a or b) are known, then the length of the other side can be calculated as
a = √(c2-b2)
or
b = √(c2-a2)

Postal Index Number (PIN) / PIN Code is a 6 digit code of Post Office numbering used by India Post. The PIN Code system in India was introduced on 15 August 1972 by Shriram Bhikaji Velankar. The system was introduced to simplify the manual sorting and delivery of mail by eliminating confusion over incorrect addresses, similar place names and different languages. .
There are 9 PIN regions in the country. The first 8 are geographical regions and the digit 9 is reserved for the Army Postal Service. The first digit indicates one of the regions. The first 2 digits together indicate the sub region or one of the postal circles. The first 3 digits together indicate a sorting district. The last 3 digits refer to the delivery Post Office. .
PIN zones cover the Indian states and union territories: .
1 - Delhi, Haryana, Punjab, Himachal Pradesh, Jammu and Kashmir, Chandigarh.
