William Oughtred(1574-1660) was the first to use the symbol for parallel.
Archimedes first used the symbol PI because he was the first one to discover it so he wanted to investigate about it.

The symbol √ for the square root was first used in print in 1525 inChristoph Rudolff's Coss, which was also the first to use the then-new signs '+' and '-'
It was a cool looking greek letter.
Rene Descartes, who has been called the Father of Modern Philosophy, used alphabetic symbols to represent mathematical ideas. For instance, he used x to denote a variable.

Descartes used the parabola to illustrate algebraic equations. He put these equations on a visible plane using the Cartesian coordinate system and they sometimes took the shape of a "u" curve, or a parabola.
Most people who use their brains and are open to thought will appreciate the beauty of mathematics. Some are able mathematicians, other less so. Descartes was one of the more able people.
Descartes' mathematical formulas are used frequently in geometry. His slope theory and other algebraic formulas related to the geometric plane are still the standard in mathematics and his ideas helped form the basis of modern calculus.
Watching a fly fly about in his room and realised he could use three coordinates to give it's position in space.
Descartes did not discover geometry - he invented analytical geometry, which enabled mathematicians to use algebra to solve problems in geometry and geometry to solve problems in algebra. The world would be less developed than now, as would be the case with most discoveries.
Rene Descarite
Yes, math would be different without René Descartes' discovery of analytic geometry. Descartes developed the Cartesian coordinate system, which introduced the use of algebraic equations to describe geometric shapes. This synthesis of algebra and geometry revolutionized mathematics, allowing for the development of new mathematical techniques and theories.

The religious beliefs of René Descartes have been rigorously debated within scholarly circles. He claimed to be a devout Roman Catholic, claiming that one of the purposes of theMeditations was to defend the Christian faith. However, in his own era, Descartes was accused of harboring secret deist or atheist beliefs. Contemporary Blaise Pascal said that "I cannot forgive Descartes; in all his philosophy, Descartes did his best to dispense with God. But Descartes could not avoid prodding God to set the world in motion with a snap of his lordly fingers; after that, he had no more use for God."[24]Stephen Gaukroger's biography of Descartes reports that "he had a deep religious faith as a Catholic, which he retained to his dying day, along with a resolute, passionate desire to discover the truth."[25] After Descartes died in Sweden, Queen Christina abdicated her throne to convert to Roman Catholicism (Swedish law required a Protestant ruler). The only Roman Catholic with whom she had prolonged contact was Descartes, who was her personal tutor.[citation needed]
