Explain about Pi: The value of Pi (π) is the ratio of the circumference of a circle to its diameter and is approximately equal to 3.14159. In a circle, if you divide the circumference (is the total distance around the circle) by the diameter, you will get exactly the same number. Explain about Phi: 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. Explain about Tau: Tau (τ) (/ˈtɔː, ˈtaʊ/) is a mathematical constant that is the ratio of a circle's circumference to its radius. This produces a number, and that number is always the same. However, the number is rather strange. The number starts as 6.283185307179586 and continues without end. Well i only know about Pi, Phi and Tau i google it.
