Gosh… I was so confused with pi, I had so many questions like, “Why is pi used for formulae regarding to circle?” “What does pi means?”. This video cleared EVERY DOUBTS I HAD.. Thank you so much 😊

I'm so grateful. I used to calculate different formulas with trigonometric circle pis without even knowing where did their values come from... Thanks alot

The number π (/paɪ/) is a mathematical constant. Originally defined as the ratio of a circle's circumference to its diameter, it now has various equivalent definitions and appears in many formulas in all areas of mathematics and physics. It is approximately equal to 3.14159. It has been represented by the Greek letter "π" since the mid-18th century, though it is also sometimes spelled out as "pi". It is also called Archimedes' constant.

Being an irrational number,  π cannot be expressed as a common fraction (equivalently, its decimal representation never ends and never settles into a permanently repeating pattern). Still, fractions such as 22/7 and other rational numbers are commonly used to approximate π. The digits appear to be randomly distributed. In particular, the digit sequence of π is conjectured to satisfy a specific kind of statistical randomness, but to date, no proof of this has been discovered. Also,  π is a transcendental number; that is, it is not the root of This transcendence of π implies that it is impossible to solve the ancient challenge of squaring the circlewith a compass and straightedge.

Ancient civilizations required fairly accurate computed values to approximate π for practical reasons, including Around 250 BC the Greek an algorithm for calculating it. In the 5th century AD Chinese mathematicsapproximated π to seven digits, while Indian mathematics made a five-digit approximation, both using geometrical techniques. The historically first exact formula for π, based on infinite series, was not available until a millennium later, when in the 14th century the Madhava–Leibniz series was discovered in Indian mathematics.[1][2] In the 20th and 21st centuries, mathematicians and computer scientists discovered new approaches that, when combined with increasing computational power, extended the decimal representation of π to many trillions of digits after the decimal point.[3][4]Practically all scientific applications require no more than a few hundred digits of π, and many substantially fewer, so the primary motivation for these computations is the quest to find more efficient algorithms for calculating lengthy numeric series, as well as the desire to break records.[5][6]The extensive calculations involved have also been used to test supercomputers and high-precision multiplication algorithms.

Because its most elementary definition relates to the circle,  π is found in many formulae in trigonometry and geometry, especially those concerning circles, ellipses, and spheres. In more modern mathematical analysis, the number is instead defined using the spectral properties of the real number system, as an eigenvalue or a period, without any reference to geometry. It appears therefore in areas of mathematics and the sciences having little to do with the geometry of circles, such as number theory and statistics, as well as in almost all areas of physics. The ubiquity of π makes it one of the most widely known mathematical constants both inside and outside the scientific community. Several books devoted to π have been published, and record-setting calculations of the digits of π often result in news headlines. Attempts to memorize the value of πwith increasing precision have led to records of over 70, 000 digits.

EXUCSE ME BUT THAT IS ACTUALLY A JAPENESE LETTER OR SOMETHING, UR USING THE WRONG SYMBOLS :/

How do we measure the circumference? Is it using ruler or some other instrument?

When we waere in schools, teachers made us to memorize PIE is equal to...bla bla but they didn't inform us what's the source of PIE....Than you very very much for opening my brain.
