**How to use complex numbers to solve trig problems Quora**

Complex numbers are convenient to represent and calculate both AC signals and impedance. The two dimensions, length and angle, allows us to calculate amplitude and â€¦... To add and subtract complex numbers: Simply combine like terms. For example, (3 â€“ 2i) â€“ (2 â€“ 6i) = 3 â€“ 2i â€“ 2 + 6i = 1 + 4i. To multiply when a complex number is involved, use one of three different methods, based on the situation:

**What are the applications of complex numbers? Quora**

To add and subtract complex numbers: Simply combine like terms. For example, (3 â€“ 2i) â€“ (2 â€“ 6i) = 3 â€“ 2i â€“ 2 + 6i = 1 + 4i. To multiply when a complex number is involved, use one of three different methods, based on the situation:... Complex numbers are the sum of a real and an imaginary number, represented as a + bi. Using the complex plane, we can plot complex numbers similar to how we plot a coordinate on the Cartesian

- Complex Numbers in Real Life Asked by Domenico Tatone (teacher), Mayfield Secondary School on Friday May 3, 1996: I've been stumped! After teaching complex numbers, my students have asked me the obvious question: Where is this math used in real life!
- Euler's Formula for Complex Numbers Note: we are using radians, not degrees. The answer is a combination of a Real and an Imaginary Number, which together is called a Complex Number. We can plot such a number on the complex plane (the real numbers go left-right, and the imaginary numbers go up-down): Here we show the number 0.45 + 0.89 i Which is the same as e 1.1i. Let's plot some â€¦
- - [Voiceover] This video's going to be a quick review of complex numbers. If you studied complex numbers in the past this will knock off some of the rust and it will help explain why we use complex numbers in electrical engineering.
- A complex number can take one of two forms: a purely imaginary number or a general complex number. 1. Purely imaginary numbers are numbers of the form I*y , where y is an integer, rational, or floating-point number and I is the square root of -1 .
