What is the upside down triangle called?
The upside down capital delta is called a Del, or Nabla from the Greek νάβλα, meaning “harp” due to the shape. (Because of the story[1], I like “nabla” better.) According to Wolfram MathWorld[2] this symbol is used to indicate gradient or other vector derivatives.
What does three dots upside down triangle mean in math?
Similar signs (below) In logical argument and mathematical proof, the therefore sign, ∴, is generally used before a logical consequence, such as the conclusion of a syllogism. The symbol consists of three dots placed in an upright triangle and is read therefore.
What does an upside down symbol mean?
Reading Time: 4 minutes. Inverted punctuation such as upside-down question marks or exclamation points are found in the languages of Spain and Latin American Spanish. This punctuation marks the beginning of interrogative or exclamatory sentences or clauses and is mirrored at the end with standard punctuation.
What is this symbol ρ?
Rho (uppercase/lowercase Ρ ρ) is the 17th letter of the Greek alphabet. It is used to represent the "r" sound in Ancient and Modern Greek. In the system of Greek numerals, it has a value of 100.
What does ∆ mean in math?
∆: Means “change” or “difference”, as in the equation of a line's slope: 2. 1. 2. 1.
What does a triangle signify?
A triangle represents manifestation, enlightenment, revelation, and a higher perspective. It is often used to mark the cycles of growth that lead to a higher state of being. Spiritually, it represents a path towards enlightenment or connection to an omnipresent being.
What does this symbol mean in mathematics?
This symbol < means less than, for example 2 < 4 means that 2 is less than 4. This symbol > means greater than, for example 4 > 2. ≤ ≥ These symbols mean 'less than or equal to' and 'greater than or equal to' and are commonly used in algebra. In computer applications <= and >= are used.
Why does Spanish use upside down punctuation?
The upside down question mark (¿) is a punctuation mark that is standard in Spanish. ... That is simply proper Spanish punctuation. It allows a reader to know the following statement is a question. The same goes for the exclamation point because it allows the reader know that the upcoming statement is an exclamation.
How do you do the upside down question mark?
Press and hold the Alt button on your keyboard (it's usually on the bottom next to the spacebar). As you're holding, type in the numbers 168 to add an upside down question mark. You can also type Alt + 0191 or Alt + 6824.
What does ⋅ mean?
The ⋅ is the same as the × multiplication sign, but it is often used in mathematical notations to prevent possible confusion with the letter 'x'. e.g. y × x is often written as y ⋅ x. ... This sign is used to represent equivalence.
How do you tell the difference between rho and P?
the rho is a single stroke, starting below the line going up, curving around and NOT quite contacting the stem. the "p" begins with a seriph, then downstroke, then up and looping to make definite contact with the stem.
What is ρ in physics?
ρ density, volume mass density.
Does a triangle mean change?
The triangle is the Greek letter delta which stands for difference. It is used for change as opposed derivative which generally assumes that a function is known. Delta is the initial letter of the Greek word διαφοράdiaphorá, "difference".
Is Pi a real numbers?
Regardless of the circle's size, this ratio will always equal pi. In decimal form, the value of pi is approximately 3.14. But pi is an irrational number, meaning that its decimal form neither ends (like 1/4 = 0.25) nor becomes repetitive (like 1/6 = 0.166666...). (To only 18 decimal places, pi is 3.141592653589793238.)
What does a triangle represent if it is before a variable?
Delta Symbol: Change
Uppercase delta (Δ) at most times means “change” or “the change” in maths. Consider an example, in which a variable x stands for the movement of an object. So, “Δx” means “the change in movement.” Scientists make use of this mathematical meaning of delta in various branches of science.
