Of course to understand this one must know a bit of vocabulary. Euler discovered that the number of faces plus the number of vertices minus the number of edges always equals two for polyhedra. This formula works for all polyhedron that do not have a hole running through it. Euler discovered a relationship between the faces, vertices and edges of a polyhedron. I thought we would look at his simple geometric formula because it is easy to understand and show to kids. For a little more challenge here is a page on pi and using Euler's methods to approximate it.Įuler has formulas in various topics in mathematics and physics. This would be for older students around high school level. ( Source) Here is a page from my teaching days on exponents, logarithms and interest. Today the number e is often referred to as Euler's number. There are many ideas but we will never know for sure. No one is sure why Euler used the letter e to represent this number. Euler also gave the decimal approximation of e to 18 places. Euler was the first to use the letter e to describe the number and the first to show thatĪnd that e is the limit of (1 + 1/ n) n as n tends to infinity (which is what Jacob Bernoulli approximated in 1683). Euler of course studied with Johann Bernoulli and continued his work. In 1697 Johann Bernoulli began the study of the calculus of the exponential function. In 1684 Scottish mathematician James Gregory understood that logarithms are the inverse functions of exponential functions, but he may not have been the first to have this understanding. In 1683 Jacob Bernoulli (Johann's brother) realized that for continually compounded interest the base must be between 2 and 3. During the 17th centur y there was work with logarithms and in 166 8 German mathematici an, Nicolaus Mercator published a paper that involved natural logarithm with the base being e but not using e. No one however gave it a name that stuck. Before Euler published about the number he would name e there was some activit y around it. The Number e The number e is approximately 2.71828. I could go on and on about his achievements but am going to focus on three. He also consistently used although it was first suggested by Welsh mathematician William Jones and reportedly was the first to use i for the square root of -1. Then there is the matter of the number e. He is also said to be the first to use the Greek letter Σ for summations. This is something that is used all the time now. He was the f irst m athemat ician to use f(x) n otation for a function. ( Source)Įuler is often referred to as t he greatest mathematician of the 18th century. Petersburg the night of S eptem ber 18, 17 83. Ho wever he was able to do the mathe matics and physics in his mind and continued to pu blish his work. However he was n ot appointed the hea d of it by King Freder ick II and he returned to St. In the 1740s he was appointed the head of the mat hematics div ision at the newly established Berlin Academy of Science and Beaux Arts. He also later ma rried her ha lf sister after Katharina died. He married Kath arina Gsell and they had many children, however only five lived past their father. Later in his life he would be in charge of the math ematics division there. He then went to Russia to teach at the S t. (The Bernoulli fam ily has several famous mathemati cians as well.) He atten ded the University of Basel and earned his master's degree while he was a teenager. He showed an aptitude for mathematics at an early age and began to work with Swiss mathematician Johan Bernoulli. Euler's Life Euler was born in Ba sel, Switzerland on April 15, 1707. ![]()
