An imaginary number is a real number multiplied by the imaginary unit i, which is defined by its property i 2 = −1. The square of an imaginary number bi is −b 2.For example, 5i is an imaginary number, and its square is −25.By definition, zero is considered to be both real and imaginary. Originally coined in the 17th century by René Descartes as a derogatory …8.1: Metric Spaces. As mentioned in the introduction, the main idea in analysis is to take limits. In we learned to take limits of sequences of real numbers. And in we learned to take limits of functions as a real number approached some other real number. We want to take limits in more complicated contexts.

A complex number is a combination of real values and imaginary values. It is denoted by z = a + ib, where a, b are real numbers and i is an imaginary number. i = √−1 − 1 and no real value satisfies the equation i 2 = -1, therefore, I is called the imaginary number.

The z-score is the number of standard deviations a data point is from the population mean. You can calculate a z-score for any raw data value on a normal distribution. When you calculate a z-score you are converting a raw data value to a standardized score on a standardized normal distribution.In today’s digital age, securing your personal information and sensitive data is more crucial than ever.
