Well I have to send this problem to a website and I think I have to make some calcules... I know that my goal is to understand how to solve it and not to receive the solution but is there anyone who can solve it so I can earn the maximum points? Thanks.
In every top of a regular polygon with 2n tops there is written an integer number so the numbers written in two neighboring tops always differ by 1 ( the numbers are consecutive )
The numbers which are bigger than both of their neighbors are called ”mountains” and those which are smaller than...
We have a,b,c different complex numbers so
(a+b)^3 = (b+c)^3 = (c+a)^3
Show that a^3 = b^3 = c^3
From the first equality I reached a^3 - c^3 + 3b(a-c)(a+b+c) = 0 How a is different from c => a-c is different from 0
How do I show that a^3 - c^3 = 0?
You didn't understand.
We say that a number x = {x} + [x]
http://en.wikipedia.org/wiki/Fractional_part
(a,n) = 1 that means the greatest common factor
Ex: (2, 3)=1
(23, 29)=1
(14, 19)=1
Hope this helps but I think
you know physics better because this notions are learned in middle school...
Hi everyone!
How to solve this: S(n) = { (a+b)/n } + { (2a+b)/n } + { (3a+b)/n } + ... + { (na+b)/n } where {x} represents fractional part of x. a,b,n are natural non-null numbers and (a,n)=1.
I don`t need only an answer, i need a good solution.
Thanks!
