Is 1 divided by 0 both negative and positive infinity What is Imaginary or Complex infinity?

Is the square root a real number?

The square roots of any positive real number are a positive and a negative real number. The square roots of any negative real number are a positive and a negative imaginary number. The square roots of any imaginary number or any complex number are two complex numbers.

How do you graph a complex equation?

"Color wheel graphs" are commonly used. At each point in the complex plane, the graph is a color, where the brightness represents the magnitude, and the hue represents the complex angle. Thus, positive values are cyan, negative values are red, and pure imaginary values are green or magenta. Other complex numbers are mixtures of these. Zero is black, and infinity is white. (Other schemes are also in use)

The set of complex numbers contains only numbers of the form a plus bi where a and b are positive numbers and you is the imaginary unit?

Not exactly. The numbers (a & b) can be any real number (positive or negative). It is the letter i, which represents the imaginary unit sqrt(-1).False

Is the square root of negative two an irrational number?

No, it is an imaginary number which is a complex number.

What are complex or imaginary numbers?

An imaginary number is a number, which when squared, gives a negative real number. Any positive or negative real number, when squared, will give a positive real number. Imaginary numbers were originally conceived (around the 1500's) to provide solutions to equations which required there be a solution to the square root of a negative real number. Originally, that was the only purpose that they served, so they were given the term imaginary. The imaginary numbers were shown to be graphically at a 90° angle to real numbers. Complex numbers are the combination of real and imaginary numbers, and can be plotted graphically on a complex plane, just like you would plot x and y coordinates on a regular 2-dimensional plane.Through the work of Euler in the 1700's and others, a relationship between imaginary numbers and the behavior of waves and oscillating motion was worked out. See related link for some interesting information about imaginary and complex numbers.

What is the square root of negative 62?

If you have not studied complex numbers, then the answer is as follows:The rules of multiplication for real numbers are thata positive times a positive is a positive, anda negative times a negative is a negative.[Also, 0 times 0 is 0].The upshot of all that is the square is never negative. And so, the answer is that there is no real number whose square is -62.If you have studied complex numbers then you should not be asking such basic questions! Still, the square roots of -62 are the complex pair Â±7.874i where i is the imaginary square root of -1.

What is the complex conjugate of negative one minus nine imaginary?

It is negative one plus nine imaginary.It is negative one plus nine imaginary.It is negative one plus nine imaginary.It is negative one plus nine imaginary.

What is the i part of a complex number?

The "i" part is the imaginary square root of negative one.

Why is the square root of a negative number imaginary?

Any real number, when squared will give a positive real number. This is true weather you have a negative real number and square it, or positive. The concept of imaginary numbers was invented to handle equations which needed to use the square root of a negative number, in order to solve them.At first, they were not considered useful beyond this, so they were named imaginary numbers. Through the work of Euler and others, it became evident that imaginary and complex numbers could be useful, especially when analyzing waves, such as electrical waveforms.

Can you divide infinity by an imaginary number?

Yes, but the answer will be in infinities within the complex domain. Unless you know what you are doing there, stay away ;)

If the discriminant is zero then there are no imaginary solutions?

Yes, if the discriminant is zero, then there will be a double root, which will be real.Also, If the discriminant is positive, there will be two distinct real solutions. But if the discriminant is negative, then you will have two complex solutions.

What is it called if something is positive or negative?

Numbers that can be positive or negative include the integers, the rational numbers, the real numbers, and the complex numbers. All integers are rational numbers (numbers that can be written as a fraction, like 2/1), but most rational numbers are not integers -- like -1/2. (2/1, a rational, can be written as 2, an integer). The real numbers include all the rationals, plus many, many more numbers that can't be written as ratios or fractions, such as the square root of 2, pi, and the euler constant, e. As with the rational numbers and integers, there are as many negative real numbers as there are positive ones. Finally, we have the complex numbers. These include all of the real numbers, plus the roots of negative real numbers. Complex numbers are written in two parts -- a real part, plus an "imaginary" part (which is just as "real" as the real part, but is called "imaginary" for historical reasons). For example, 1 + i is a complex number with positive real and imaginary parts, while -1 - i is a complex number with negative real and imaginary parts. Positive and negative number systems are clearly very important in mathematics and in everyday life. They are all distinguished by the fact that they include magnitudes less than zero, as well as greater than zero (magnitudes of complex numbers are more complicated because complex numbers can have both positive and negative parts in one complex number!) There is also the term "non-zero" which refers to values that are positive or negative but not a value that is neither. It is a very important mathematical term since many functions (reciprocals, for example) can only have non-zero domains.
