What does ≡ mean in math?

not equalIn computer applications (like Excel) the symbols <> mean not equal.

≡ means identical to.

≈ means approximately equal to, or almost equal to.

The two sides of a relationship indicated by this symbol will not be accurate enough to manipulate mathematically..

What does 4p mean in parabola?

The directrix is a horizontal line 2 units down from the vertex. The equation is y = -2 To determine how wide the parabola opens, the distance |4p| is the distance of the chord connecting the two sides of the parabola through the focus point perpendicular to the axis of symmetry.

What does P and Q stand for in logic?

First, P is the first letter of the word “proposition”. Old logic texts sometimes say something like “assume a proposition P” and then go on to prove something about P. Q is just the next letter after P, so when you need another proposition to assume, it’s an easy and convenient letter to use.

What is P and Q in logic?

Conditional Propositions. A proposition of the form “if p then q” or “p implies q”, represented “p → q” is called a conditional proposition. … The proposition p is called hypothesis or antecedent, and the proposition q is the conclusion or consequent. Note that p → q is true always except when p is true and q is false.

What 3 lines tattoo mean?

Although most that have this image on their body have it painted on instead of tattooed, many will get this tattoo on other parts of their body to get their message across instead of having it on their face. These three lines represent Shiva’s power that is threefold. These are action, knowledge and power of will.

What does the symbol * mean?

Answer and Explanation: In mathematics, the asterisk symbol * refers to multiplication.

What does P mean in logic?

P :⇔ Q means P is defined to be logically equivalent to Q. A XOR B :⇔ (A ∨ B) ∧ ¬(A ∧ B)

What does Big P mean in math?

The Pi symbol, , is a capital letter in the Greek alphabet call “Pi”, and corresponds to “P” in our alphabet. It is used in mathematics to represent the product (think of the starting sound of the word “product”: Pppi = Ppproduct) of a bunch of factors.

What is P in geometry?

Perimeter (of base) What does capital P stand for? Height of Prism.

What is p value in parabola?

The absolute value of p is the distance between the vertex and the focus and the distance between the vertex and the directrix. (The sign on p tells me which way the parabola faces.) Since the focus and directrix are two units apart, then this distance has to be one unit, so | p | = 1.

What is P in an equation?

focus is traditionally labeled as “p”. … p is the distance from the vertex to the focus. You remember the vertex form of a parabola as being y = a(x – h)2 + k where (h, k) is the vertex of the parabola. If we let the coefficient of x2 (or a) = and perform some algebraic maneuvering, we can get the next equation.

What is P in a parabola?

The point P is a typical point on the parabola so that its distance from the directrix, PQ, is equal to its distance from F, PF. The point marked V is special. It is on the perpendicular line from F to the directix.

What does [] mean in math?

if using this in sets, () stands for open interval and [] means closed interval and {} is used to denote specific elements. Closed interval means the extreme numbers of the set are included in it and open means they arent. For example, (9,10] is the set of all numbers between 9 and 10 excluding 9 and including 10.
