"why" is not a mathematical symbol.
Sir Isaac Newton
The first known use of the symbol π to represent the mathematical constant approximately equal to 3.14159... was by Welsh mathematician William Jones in 1706. However, it was the Swiss mathematician Leonhard Euler who popularized the use of π in his mathematical works and made it widely recognized.
The pi symbol (π) was first assigned to represent the mathematical constant in 1706 by Welsh mathematician William Jones. He introduced it in his work "Synopsis Palmariorum Matheseos," where he used the symbol to denote the ratio of a circle's circumference to its diameter. The symbol gained widespread popularity after being adopted by the mathematician Leonhard Euler in the 18th century.
Generally that's != or it could be <>. A != B A <> B Both are "A is not equal to B" but the first is more common. EDIT: the symbols above are used in programming, but in more simple mathematics the symbol is a ( =/= ) where an equal symbol ( = ) is slashed.
Pi as a mathematical symbol was introduced by William Jones in 1706
The radical symbol for square root, without the vinculum above the radicand, was introduced in 1525. The first author to use it was Christoff Rudolff.
