Imaginary numbers explanation
WitrynaBut perhaps we should start with an explanation of what an imaginary number is. We know by now how to square a number (multiply it by itself), and we know that negative numbers make a positive number when squared; a minus times a minus is a plus, remember? So (–2) × (–2) = 4. We also know that taking a square root is the inverse … WitrynaUnit Imaginary Number. 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) …

Witryna在数学中,虚数就是形如a+b*i的数,其中a,b是实数,且b≠0,i² = - 1。虚数这个名词是17世纪著名数学家笛卡尔创立,因为当时的观念认为这是真实不存在的数字。后来发现虚数a+b*i的实部a可对应平面上的横轴,虚部b可对应平面上的纵轴,这样虚数a+b*i可与平面内的点(a,b)对应。 Witryna5 lis 2024 · Maybe it but it really feels like the explanations I get to complex numbers are lacking somewhere. $\endgroup$ – OzOz.

Witryna17 lip 2014 · 65. It appears to be, as you guessed, because Python follows the electrical engineering convention. Here's an exchange from the Python bug tracker Issue10562: Boštjan Mejak: In Python, the letter 'j' denotes the imaginary unit. It would be great if we would follow mathematics in this regard and let the imaginary unit be denoted with an 'i'.
Witryna8 lip 2024 · An imaginary number raised to an imaginary number turns out to be real. However, while learning complex analysis, one learns that an exponential with respect to an imaginary number does not have a single, fixed value. Rather, the function is multi-valued — the value we arrived at in our calculation is just one of many values.
