The industrial complex is a socioeconomic concept wherein businesses become entwined in social or political systems or institutions, creating or bolstering a profit economy from these systems. Such a complex is said to pursue its own interests regardless of, and often at the expense of, the best interests of society and individuals.
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.
[6] [7] [8] Quizlet's blog, written mostly by Andrew in the earlier days of the company, claims it had reached 50,000 registered users in 252 days online. [9] In the following two years, Quizlet reached its 1,000,000th registered user. [10] Until 2011, Quizlet shared staff and financial resources with the Collectors Weekly website. [11]
The effect of industrialisation shown by rising income levels in the 19th century, including gross national product at purchasing power parity per capita between 1750 and 1900 in 1990 U.S. dollars for the First World, including Western Europe, United States, Canada and Japan, and Third World nations of Europe, Southern Asia, Africa, and Latin America [1] The effect of industrialisation is also ...
In probability theory and statistics, complex random variables are a generalization of real-valued random variables to complex numbers, i.e. the possible values a complex random variable may take are complex numbers. [1] Complex random variables can always be considered as pairs of real random variables: their real and imaginary parts ...
Binary coding systems of complex numbers, i.e. systems with the digits = {,}, are of practical interest. [9] Listed below are some coding systems , (all are special cases of the systems above) and resp. codes for the (decimal) numbers −1, 2, −2, i. The standard binary (which requires a sign, first line) and the "negabinary" systems (second ...
The system is designed to be largely compatible with the United Nations Statistical Office's International Standard Industrial Classification system (ISIC). NAICS versions are released every five years. With the first version, released in 1997, NAICS offered enhanced service sector coverage relative to the SIC.
On the region consisting of complex numbers that are not negative real numbers or 0, the function is the analytic continuation of the natural logarithm. The values on the negative real line can be obtained as limits of values at nearby complex numbers with positive imaginary parts.
