The band's name is sometimes abbreviated as D.A.I., alluding to the fact that Do As Infinity was named after Dai Nagao. Signed to Avex Trax, the band released their debut single "Tangerine Dream" on September 29, 1999, followed by three more singles between 1999 and 2000, which appeared on their debut album "Break of Dawn" (2000).

Problem: Information: - A complex number is a number that can be expressed in the form , where and are real numbers and is the imaginary unit, satisfying the equation . In this expression, is the ' and is the ' of the complex number. If formula_1, then formula_2 - Mathematics (from Greek "mathma", knowledge, study, learning) is the study of topics such as quantity (numbers), structure, space, and change. There is a range of views among mathematicians and philosophers as to the exact scope and definition of mathematics. - In mathematics, the complex plane or "z"-plane is a geometric representation of the complex numbers established by the real axis and the perpendicular imaginary axis. It can be thought of as a modified Cartesian plane, with the real part of a complex number represented by a displacement along the x-axis, and the imaginary part by a displacement along the y-axis. - A definition is a statement of the meaning of a term (a word, phrase, or other set of symbols). Definitions can be classified into two large categories, intensional definitions (which try to give the essence of a term) and extensional definitions (which proceed by listing the objects that a term describes). Another important category of definitions is the class of ostensive definitions, which convey the meaning of a term by pointing out examples. A term may have many different senses and multiple meanings, and thus require multiple definitions. - In mathematics , arg is a function operating on complex numbers ( visualized in a complex plane ) . It gives the angle between the positive real axis to the line joining the point to the origin , shown as in figure 1 , known as an argument of the point . - In mathematics, a real number is a value that represents a quantity along a line. The adjective "real" in this context was introduced in the 17th century by Rene Descartes, who distinguished between real and imaginary roots of polynomials.
