Insertion Sort – Worst Case Analysis
... We've established in class that the best case for insertion sort, the one which will cause insert(L, i) to perform the fewest number of steps is when L[i] >= max(L[:i]). Since the sublist L[:i] is sorted, the requirement becomes L[i] >= L[i-1]. In other words, the best case scenario arises when the ...

A relation between partitions and the number of divisors
... 1. Clearly, the series (1 + X n−i + X 2(n−i) + . . .) contributes +1 to the coefficient αm of X m if and only if n − i is a divisor of m. As i increases from 0 to n − 1, the number n − i decreases from n to 1. In this range there are d(m) numbers which divide m, so there are d(m) series (1 + X n−i ...

Therefore, (n − 1)! being the product of the numbers from 1 to n − 1 includes among its divisors the greatest prime factor of n, and indeed all its proper divisors. In fact, for composite n > 4, it is the case that (n − 1)! ...

Mathematics of radio engineering
The mathematics of radio engineering is the mathematical description by complex analysis of the electromagnetic theory applied to radio. Waves have been studied since ancient times and many different techniques have developed of which the most useful idea is the superposition principle which apply to radio waves. The Huygen's principle, which says that each wavefront creates an infinite number of new wavefronts that can be added, is the base for this analysis.
