A Certain Magical Index is a fighting game developed by Shade for the PlayStation Portable and published by ASCII Media Works, with Kadokawa Games in charge of sales, [1] on January 27, 2011. [2] ASCII Media Works later developed a revised edition of the game titled A Certain Magical Index PSP the Best , which was released by Kadokawa Games on ...
Then because the real part has to be zero: d 4 = d 2 = d 0 = d −2 = 0. For the imaginary part, if d 5 = d 3 = d −3 = 0 and when d 1 = 1 and d −1 = 2 the digit string can be found. Using the above coefficients in the digit string the result is: =.
A complex number can be visually represented as a pair of numbers (a, b) forming a vector on a diagram called an Argand diagram, representing the complex plane. Re is the real axis, Im is the imaginary axis, and i is the "imaginary unit", that satisfies i 2 = −1.
An imaginary number is the product of a real number and the imaginary unit i, [note 1] which is defined by its property i 2 = −1. [1] [2] The square of an imaginary number bi is −b 2. For example, 5i is an imaginary number, and its square is −25. The number zero is considered to be both real and imaginary. [3]
Substituting r(cos θ + i sin θ) for e ix and equating real and imaginary parts in this formula gives dr / dx = 0 and dθ / dx = 1. Thus, r is a constant, and θ is x + C for some constant C. The initial values r(0) = 1 and θ(0) = 0 come from e 0i = 1, giving r = 1 and θ = x.
The imaginary unit or unit imaginary number (i) is a mathematical constant that is a solution to the quadratic equation x 2 + 1 = 0. Although there is no real number with this property, i can be used to extend the real numbers to what are called complex numbers , using addition and multiplication .
