What is phi as a number?
What Is Phi? Phi is an irrational mathematical constant, approximately 1.618.., and is often denoted by the Greek letter φ. Other commonly used names for Phi are: Golden Mean, Extreme and Mean Ratio, Divine Proportion and Golden Ratio. Phi is a naturally occurring ratio which exhibits aesthetically pleasing properties.
How is phi measured?
Phi is most often calculated using by taking the square root of 5 plus 1 and divided the sum by 2:
- √5 + 1.
- BC = √5.
- DE = 1.
- BE = DC = (√5-1)/2+1 = (√5+1)/2 = 1.618 … = Phi.
- BD = EC = (√5-1)/2 = 0.618… = phi.
Is φ a real number?
Phi ( Φ = 1.618033988749895… ), most often pronounced fi like “fly,” is simply an irrational number like pi ( p = 3.14159265358979… ), but one with many unusual mathematical properties. Unlike pi, which is a transcendental number, phi is the solution to a quadratic equation.
What is phi used for?
Under HIPAA PHI is considered to be any identifiable health information that is used, maintained, stored, or transmitted by a HIPAA-covered entity – a healthcare provider, health plan or health insurer, or a healthcare clearinghouse – or a business associate of a HIPAA-covered entity, in relation to the provision of …
How do you write phi?
In English, φ is pronounced like “f” but transliterated (re-written) as “ph” in words which originate in Ancient Greek. In those words which originate in Modern Greek, such as feta cheese, φ is transliterated as “f”. The letter Phi is used to represent the golden ratio (which is about 1.618).
Why is phi so important?
PHI is important to individuals and valuable to hackers which makes it vital for organizations to protect. HIPAA lays out all the requirements and safeguards that should be put in place so that each person’s identifiable health information is kept secure from cyber criminals.

What do the numbers mean in the base system?
By analogy with the way representing numbers in a base is usually done, you’d have to start with (base pi on the left, base ten on the right): So it is fairly easy to figure out what numbers mean in this base system, although any finite decimal will be a multiple of pi plus one, two, or
What is the ratio determined by Phi?
The ratio, or proportion, determined by Phi (1.618 …) was known to the Greeks as the “dividing a line in the extreme and mean ratio” and to Renaissance artists as the “Divine Proportion” It is also called the Golden Section, Golden Ratio and the Golden Mean. Phi, like Pi, is a ratio defined by a geometric construction
