Problem 30 zWhich of the following is a true story about a famous woman mathematician? Hypatia was the first recognized women mathematician. She was born in Alexandria, Egypt, around 350AD and was a recognized scholar. Besides being a mathematician, she was an astute astronomer and a philosopher. An angry Christian mob killed her. * She wrote a commentary on the 13th volume of the famous Greek mathematics text book, 'Arithmetica'. * She edited Ptolemy's famous version of the 'Almagest'. * She edited her father's commentary on 'Euclid's Elements'. Maria Gaetana Agnesi was a child prodigy, an Italian linguist and a math wizard. Born in a wealthy family in 1718, she was the 21st child of her parents. She was fluent in 6 languages. Some of her contributions are as follows: * She wrote the first book introducing integral and differential calculus. * She determined the equation of a peculiar curve, which came to be known as the 'Witch of Agnesi'. Marie Sklodowska Curie was born in 1868 in Poland, eventually becoming a famous biologist and mathematician in Germany. She was the first woman professor at the University of Stutgart and developed the mathematical theory behind radiocarbon dating. A.Hypatia B.Hypatia and Maria Agnesi C.Maria Agnesi and Marie Curie D.Hypatia and Marie Curie E. All of the above
