x[n] = z^n for n from -infinity to infinity, z some complex number You should start with a clear graphical intuition about what such sequences are like. If the number z happens to be one or zero, we will get a sequence of constant values. If z is a positive real number, we will get a sampled exponential ramp, that is either rising or falling.

A continuous random variable X follows a normal distribution if it has the following probability density function (p.d.f.):. The parameters of the distribution are m and s 2, where m is the mean (expectation) of the distribution and s 2 is the variance. We write X ~ N(m, s 2) to mean that the random variable X has a normal distribution with parameters m and s 2.

Fermat's Last Theorem. Fermat's last theorem (also known as Fermat's conjecture, or Wiles' theorem) states that no three positive integers x,y,z x,y,z satisfy x^n + y^n = z^n xn + yn = zn for any integer n>2 n > 2. Although a special case for n=4 n = 4 was proven by Fermat himself using infinite descent, and Fermat famously wrote in the margin.

Overview Pythagorean origins. The Pythagorean equation, x 2 + y 2 = z 2, has an infinite number of positive integer solutions for x, y, and z; these solutions are known as Pythagorean triples (with the simplest example being 3, 4, 5). Around 1637, Fermat wrote in the margin of a book that the more general equation a n + b n = c n had no solutions in positive integers if n is an integer greater.

De Moivre's formula. In mathematics, de Moivre's formula (also known as de Moivre's theorem and de Moivre's identity) states that for any real number x and integer n it holds that. where i is the imaginary unit ( i2 = −1 ). The formula is named after Abraham de Moivre, although he never stated it in his works. [1]

$(\Bbb Z/n\Bbb Z)^\times$ often means the group of units.It consists of all the elements in $\Bbb Z/n \Bbb Z$ that have an inverse. These elements form a group with multiplication. Example: $\Bbb Z/4\Bbb Z=\{0,1,2,3\}$ form a group with respect to addition $\langle\Bbb Z/4\Bbb Z, +\rangle$ To form a group with multiplication, with the same set, we need to throw out some elements.

You found an nxn matrix with determinant 0, and so the theorem guarantees that this matrix is not invertible. What "the following are equivalent" means, is that each condition (1), (2), and (3) mathematically mean the same thing. It is not saying that every nxn matrix has a nonzero determinant.
