In programming languages, q % p is the remainder of q divided by p. Mathematicians more commonly notate a similar operation as q ( mod p), except that q % p returns specifically an integer from { 0, 1, 2, …, p − 1 } whereas q ( mod p) technically returns an equivalence class r + p Z. Often ( mod p) has the same use however.

The formula for a quadratic equation is used to find the roots of the equation. Since quadratics have a degree equal to two, therefore there will be two solutions for the equation. Suppose ax² + bx + c = 0 is the quadratic equation, then the formula to find the roots of this equation will be: x = [-b±√ (b2-4ac)]/2a.The letters R, Q, N, and Z refers to a set of numbers such that: R = real numbers includes all real number [-inf, inf] Q= rational numbers ( numbers written as ratio) Mar 8, 2017 · In Statistics, it is used to indicate that a variable follows a certain distribution. So, for example, X ∼ N(μ,σ2) X ∼ N ( μ, σ 2) can be read as " X X behaves according to a Normal distribution". This is the usage relevant in the image in question.

In LaTeX it is coded as \cong. ∼ ∼ is a similarity in geometry and can be used to show that two things are asymptotically equal (they become more equal as you increase a variable like n n ). This is a weaker statement than the other two. In LaTeX it is coded as \sim. ≃ ≃ is more of a grab-bag of meaning.B is the divisor. Q is the quotient. R is the remainder. Sometimes, we are only interested in what the remainder is when we divide A by B . For these cases there is an operator called the modulo operator (abbreviated as mod). Using the same A , B , Q , and R as above, we would have: A mod B = R.

Q.E.D. Q.E.D. or QED is an initialism of the Latin phrase quod erat demonstrandum, meaning "which was to be demonstrated". Literally it states "what was to be shown".

Sup ("supremum") means, basically, the largest. So this: sup k≥0 T(k)(N) sup k ≥ 0 T ( k) ( N) refers to the largest value T(k)(N) T ( k) ( N) could get to as k k varies. It's technically a bit different than the maximum—it's the smallest number that is greater-than-or-equal to every number in the set.

In mathematics, a prime number is any whole number greater than one that has no positive factors other than one and itself. For example, the number 17 is prime, because its only factors are one and 17.
