How Did Leonard Euler Contribute to Mathematics?

Leonard Euler largerly contributed to the field of mathematics by proving existing theorems, finding the solutions to complex problems, introducing mathematical symbols and formulating theorems and equations that bear his name. Euler is considered to be the most prolific and one of the most influential scientists, with some claiming that he was the greatest mathematician during the 1700s.

Euler was involved in various aspects of mathematics and physics, which include graph theory, number theory, calculus, trigonometry, topology, fluid mechanics, optics, magnetism and electricity. Euler is credited with inventing the symbols "e," "f(x)" and "i," which is the symbol for the square root of a negative number. Euler's major contributions that were named after him include Euler's formula, Euler's theorem, Euler angles, Euler-Lagrange equation, Euler numbers, Eulerian numbers and Euler primes.
