Teacher: Now, understand the problem? Solve this instance: Passage: Witold Wilkosz was born on 14 August 1891 in Krakow to parents Jan, a Polish teacher, and Jozefa nee Vopalko. He showed a considerable talent for mathematics and languages since early childhood. He passed his final school-leaving Matura exam at the John III Sobieski High School (known in Poland as Gimnasium). He was a friend of fellow mathematician Stefan Banach. Before graduating from high school, he had written an article on semitology for which he was offered a scholarship and membership from Morgenlandische Gesselchaft Scienctific Society, which enabled him to study at the University of Beirut. After a few months, he returned to Krakow and took up philology studies at the Jagiellonian University. After two years, he decided to change the course to mathematics, which he studied in Krakow and Turin. He received his doctoral degree on the basis of his dissertation on Lebesgue integrals and started to work as an academic teacher at his alma mater. In 1920, he obtained a habilitation and in 1936 he became a professor. He was arrested on 6 November 1939 by Nazi Germans alongside other prominent intellectuals and professors of Krakow in the infamous Sonderaktion Krakau. However, due to a serious illness, he was soon released together with nine other professors on 9 November. He returned home and began to work as a teacher. To supplement his income, he accepted another job at the Powszechny Zakad Ubezpieczen Wzajemnych insurance company. In the following years, his health seriously deteriorated. He died of pneumonia on 31 March 1941.
Link Information: In mathematics, the integral of a non-negative function of a single variable can be regarded, in the simplest case, as the area between the graph of that function and the -axis. Answer: the integral of a non-negative function of a single variable
