Mathematicians once turned up their noses at imaginary numbers. But complex analysis actually simplifies math and physics.

the world of complex analysis. For one, trigonometry becomes a lot easier. Instead of memorizing several complicated trig formulas, you need only one equation to rule them all: Euler's 1740 formula.

Even mathematical giants found complex numbers difficult to swallow ... you need only one equation to rule them all: Euler’s 1740 formula. With decent algebra skills, you can manipulate Euler ...

Euler's formula relies on imaginary numbers. (Raina Okonogi-Neth) Calculus becomes easier, too. As mathematicians Roger Cotes, René Descartes – who coined the term "imaginary number" – and others have ...

The zeta functions arising in seemingly different scenarios tend to have some features in common: meromorphic extension to the complex plane, location of poles and zeros, the Euler product formula, ...

Just as the infant formula crisis of 2022 has receded from the collective memory of American parents comes word of a new formula fiasco: presence of harmful contaminants, including arsenic and ...
