Noun1.imaginary number- (mathematics) a number of the form a+bi where a and b are real numbers and i is the square root of -1 complex number,complex quantity,imaginary math,mathematics,maths- a science (or group of related sciences) dealing with the logic of quantity and shape and arran...
The square root of minus one √(−1) is the "unit" Imaginary Number, the equivalent of 1 for Real Numbers.In mathematics the symbol for √(−1) is i for imaginary.But in electronics the symbol is j, because i is used for current, and j is next in the alphabet....
Imaginary numbers can be used to find roots of polynomials when some or all of the roots are not real numbers. Imaginary numbers also have enormous usage in physics, where they are used to model light waves, sound waves, and even alternating current in the study of electricity. They are al...
Have you ever sat in a math classroom and wondered, “When will I ever use this?” You might have asked yourself this question when you first encountered “imaginary” numbers, and with good reason: What could be less practical than a number described as imaginary? 你是否会坐在数学教室里,...
5.Because no real number x satisfies the equation x2+ 1 = 0, mathematicians built a new number system—now known as the complex numbers—by adding an imaginary number i and imposing the stipulation that i2 + 1= 0. 6.Math has many important constants that give the discipline structure, ...
Imaginary numbers are numbers that have a negative result when they are squared. Imaginary numbers have the value of −1 and are represented by the letter i. In math we are used to squaring a number (multiplying a number by itself), but we are also used to receiving positive answers. ...
I wrote the \(=\) sign there, because that way I know that \(\frac{1}{2}\) and \(\frac{3}{6}\) have indeed different numbers, but they are on the same height. You can have a look at the picture again. (…) In this excerpt we also see how written and spoken language mer...
