WebAnswer (1 of 4): I think you meant “name”, not “expansion”—there is no expansion for the imaginary number i, whose symbol is the first letter of “imaginary”. Thus, it is the ordinary Latin letter i, not the Greek letter ι. This is the notation used by the vast majority of mathematicians and physi...
WebComplex numbers are used in many scientific fields, including engineering, electromagnetism, quantum physics, and applied mathematics, such as chaos theory. Complex numbers allow for solutions to certain equations that have no real number solutions. For example, the equation: (x + 1)^2 = -9 (x+ 1)2 = −9. where e is the base of the natural logarithm, i is the imaginary unit, and cos and sin are the trigonometric functions cosine and sine respectively. This complex exponential function is sometimes denoted cis x ("cosine plus i sine"). The formula is still valid if x is a complex number, and so some authors refer to … See more Euler's formula, named after Leonhard Euler, is a mathematical formula in complex analysis that establishes the fundamental relationship between the trigonometric functions and the complex exponential function. … See more The exponential function e for real values of x may be defined in a few different equivalent ways (see Characterizations of the exponential function). Several of these methods may be directly extended to give definitions of e for complex values of z simply by … See more • Complex number • Euler's identity • Integration using Euler's formula • History of Lorentz transformations § Euler's gap See more • Elements of Algebra See more In 1714, the English mathematician Roger Cotes presented a geometrical argument that can be interpreted (after correcting a misplaced factor of $${\displaystyle {\sqrt {-1}}}$$) … See more Applications in complex number theory Interpretation of the formula This formula can be interpreted as saying that the function e is a unit complex number, i.e., it traces out the unit circle in the complex plane as φ ranges through the real numbers.
