Imaginary, or more precisely complex numbers (vectors that have a real part and an imaginary part) are used in a variety of fields, including:
An imaginary number is simply a number that contains 'i' which is simply shorthand for the square root of minus one. In the same way, we can write the square root of other negative numbers using i as a factor. For example;Sqrt(-64) = Sqrt(-1*64) = Sqrt(-1)*Sqrt(64) = i*8 = 8iThere are also 'complex numbers' which are simply combinations of real numbers (all positive and negative numbers) and imaginary numbers. For example;2+3iIs a complex number. Although these numbers seem not to "exist" (it's impossible to have a set of 8i golf balls, or for you to weigh 3i kg) they are very useful in the fields of mathematics, physics, and engineering, and allowing their existence can save a lot of trouble when it comes to doing difficult math.
Real numbers, Rational numbers, and Integers.The other three are Irrational (numbers that cannot be expressed as fractions), Whole numbers (0,1,2,3,4...) and Natural numbers (1,2,3,4,5...).EDIT: There is also imaginary numbers (√-1, often expressed as i ) and complex numbers (numbers that contain both a real and imaginary part i.e. a+bi where a and b are real numbers and i is an imaginary number)
The horizontal plane is an imaginary flat surface that runs parallel to the horizon, dividing the space into upper and lower sections. It is often associated with levels of elevation, like floors in a building. The vertical plane, on the other hand, is an imaginary surface that runs perpendicular to the horizontal plane, dividing space into left and right sections. Together, these planes help define three-dimensional space in various fields, including geometry, physics, and architecture.
The multiplicative identity is a fundamental concept in mathematics, referring to the number that, when multiplied by any other number, leaves that number unchanged. In the set of real numbers, the multiplicative identity is 1. For example, multiplying any number by 1 results in the original number, such as (5 \times 1 = 5). This property is essential in various mathematical operations and simplifies computations in algebra and other fields.
Every integer (whole numbers, including positives, negatives, and zero) is either odd or even. No number is both odd and even. Other numbers, such as fractions that don't reduce to an integer, irrational numbers, and pure imaginary numbers are neither odd nor even. Zero is an even number and is not an odd number.
A non complex number is a number that does not have any imaginary component. An imaginary component is a non zero factor of the square root of -1, in other words, the imaginary number i.
the number in the root should be a positive number other wise the answer is going to be an imaginary number
A complex number, in my life, is a number which is composed of two parts: one part which is a real number and the other which is imaginary. It can be represented by a point in a coordinate plane.
Always. The set of imaginary numbers is a subset of complex numbers. Think of complex numbers as a plane (2 dimensional). The real numbers exist on the horizontal axis. The pure imaginary are the vertical axis. All other points on the plane are combinations of real and imaginary. All points on the plane (including imaginary axis and real axis) are complex numbers.
Imaginary lines of force around a magnet are called magnetic field lines. They represent the direction and strength of the magnetic field. These lines provide a visual way to understand how magnetic fields behave and interact with other magnets or magnetic materials.
A unit circle is in the coordinate plane where both axes are measured in real numbers. The imaginary circle is in the complex plane in which one axis (horizontal) measures the real component of a complex number and the other axis measures the imaginary component.
The Equator is slightly bigger then any of the other imaginary lines.

It would be an imaginary number (one that cannot exist). For example the square root of a negative number.
A number field will not accept text. If it does accept text, then it cannot be a number field. Text fields can accept digits, but number fields cannot accept other text. They will only accept digits and other numeric components, like a decimal point for example. Sometimes you will define a field for numbers, such as phone number or code numbers to be text fields. In fact, that is what you should do for that type of data. You never do calculations with phone numbers, like adding them or getting averages, so they can be stored in text fields, as there is no need for them to be stored in number fields. Also, a zero at the start of a phone number, would disappear if entered into a number field, and it would also not allow things like spaces or brackets.
The square root of a negative real number is an imaginary number.We know square root is defined only for positive numbers.For example,1) Find the square root of (-1)It is imaginary. We say that square root of (-1) is i.In fact they are not real numbers.2) Find the square root of (-4)-4 can be written as (-1)(4)Square root of 4 is 2 and square root of (-1) is iSo, the square root of -4 is 2i.Similarly, we can find the square root of other negative numbers also.Source: www.icoachmath.comAn imaginary number is defined to handle square roots of negative numbers. The imaginary unit i is defined as the 'positive' square root of -1.
A positive real number, such as 17, has two square roots. One is the one your calculator gives you, if you use the square root function. The other is the same number, with a minus sign in front. None of these has an imaginary part. There are no additional complex roots that have a non-zero imaginary part.
