The number π (/ p aɪ /) is a mathematical enalneupomannterg.safftitinadibnoedrumemimpherweistav.co is defined as the ratio of a circle's circumference to its diameter, and it also has various equivalent enalneupomannterg.safftitinadibnoedrumemimpherweistav.co appears in many formulas in all areas of mathematics and enalneupomannterg.safftitinadibnoedrumemimpherweistav.co is approximately equal to It has been represented by the Greek letter "π" since the midth century, and is spelled out as "pi".

For a bonding MO with π-symmetry the orbital is π u because inversion through the center of symmetry for would produce a sign change (the two p atomic orbitals are in phase with each other but the two lobes have opposite signs), while an antibonding MO with π-symmetry is π g because inversion through the center of symmetry for would not.

π 0, π +, and π −. Each pion consists of a quark and an antiquark and is therefore a meson. Pions are the lightest mesons and, more generally, the lightest hadrons. They are unstable, with the charged pions π + and π − decaying after a mean lifetime of nanoseconds ( × 10 −8 seconds), and the neutral pion π 0Discovered: César Lattes, Giuseppe Occhialini .

The same is true for the four other trigonometric functions. By observing the sign and the monotonicity of the functions sine, cosine, cosecant, and secant in the four quadrants, one can show that 2 π is the smallest value for which they are periodic (i.e., 2 π is the fundamental period of these functions).

There are several closely related functions called Jacobi theta functions, and many different and incompatible systems of notation for them. One Jacobi theta function (named after Carl Gustav Jacob Jacobi) is a function defined for two complex variables z and τ, where z can be any complex number and τ is the half-period ratio, confined to the upper half-plane, which means it has positive.

Matematička konstanta π se često koristi u matematici i fizici. 'π' je malo slovo grčkog alfabeta i menja se sa pi kada je nedostupno. U euklidskoj planimetriji, π se može definisati kao odnos obima i prečnika kruga, ili kao površina kruga poluprečnika 1 (jediničnog kruga).Većina novijih udžbenika definiše π analitički, koristeći trigonometrijske funkcije, na primer kao.
