# Complex Numbers

Complex numbers are numbers of the form a + ⅈb, where a and b are real and ⅈ is the imaginary unit. They arise in many areas of mathematics, including algebra, calculus, analysis and the study of special functions, and across a wide range of scientific and engineering disciplines. Oftentimes, they form connections between fields, for example with Euler's formula, which relates imaginary numbers to trigonometry and exponentiation. Use Wolfram|Alpha’s power and computational understanding to work with complex numbers, as well as the larger area of complex analysis, and to express them in different forms.
