### 1. Complex Numbers - Basic Definitions

31/12/2018 · Let's first consider what we learned before in Quadratic Equations and Equations of Higher Degree, so we can better understand where complex numbers are coming from.. Quadratic Equations. Examples of quadratic equations: 2x^2 + 3x − 5 = 0 x^2 − x − 6 = 0 x^2 = 4 The roots of an equation are the x-values that make it "work" We can find the roots of a quadratic …

### Modulus and Argument of a Complex Number - Calculator

Note Since the above trigonometric equation has an infinite number of solutions (since $$\tan$$ function is periodic), there are two major conventions adopted for the rannge of $$\theta$$ and let us call them conventions 1 and 2 for simplicity.

### Quadratic Equations with Complex Solutions ...

The roots belong to the set of complex numbers, and will be called "complex roots" (or "imaginary roots "). These complex roots will be expressed in the form a ± bi . A quadratic equation is of the form ax 2 + bx + c = 0 where a, b and c are real number values with a not equal to zero.

### Imaginary Numbers, How to simplify imaginary numbers ...

Imaginary numbers are based on the mathematical number $$i$$. $$i \text { is defined to be } \sqrt{-1}$$ From this 1 fact, we can derive a general formula for powers of $$i$$ by looking at some examples.

### Complex numbers | Algebra 2 | Math | Khan Academy

Complex numbers are built on the idea that we can define the number i (called "the imaginary unit") to be the principal square root of -1, or a solution to the equation x²=-1. From this starting point evolves a rich and exciting world of the number system that encapsulates everything we have known before: integers, rational, and real numbers.

### 2.4 Complex Numbers - College Algebra | OpenStax

A complex number is the sum of a real number and an imaginary number. A complex number is expressed in standard form when written a + b i a + b i where a a is the real part and b b is the imaginary part. For example, 5 + 2 i 5 + 2 i is a complex number. So, too, is 3 + 4 i 3. 3 + 4 i 3.
