The author discusses a pattern on how to find the sum of n consecutive numbers. He notes that a square number is always at the beginning of the left-hand side (LHS) of an equation. The pattern may be used for all natural numbers. A triangular, square and cube number sequence is seen...

In this example, the sum of first 10 natural numbers is displayed. First, input the value of n (10 in this case) i.e. number of natural numbers whose sum is to be calculated. Then, after initializing the variables i to 1 and sum to 0, we enter the do-whi
Math Formula to compute the Difference Between Sum of Squares and Square of the Sum We know the Sum of first N Natural numbers is: . It would be great if we can find out the formula for the sum of squares. Let’s assume is it (the sum of squares) ...
n↑(r)+n↓(r)≡2n0; however there is a spin polarization (A.7) Since F(x)≈cosx/x3 for large x, we see that the spin polarization is of long-range nature, oscillates with distance and falls off with the inverse cube power law r-3 at large distances; notice the analogies between...
