Complex numbers are helpful in finding the square root of negative numbers. The concept of complex numbers was first referred to in the 1st century by a greek mathematician, Hero of Alexandria when he tried to find the square root of a negative number. But he merely changed the negative ...
A complex number is any number that can be written in the form a + bi where a and b are real numbers. a is called the real part, b is called the imaginary part, and i is called the imaginary unit.Where did the i come from in a complex number ? A little bit of history!

Then, a typical complex number is written in the form a + bi where a and b are real numbers. In this case, a is the real part and bi is the imaginary part. Note that a can equal zero, so the complex number can just be of the form bi. Some examples of complex numbers include ...
Addition and subtraction of complex numbers is straightforward. Real and imaginary parts are added/subtracted to get the result. Example: Arithmetic Operation on Complex Numbers Copy a=6+4j b=3+2j print("a+2=",a+2) print("a*2=",a*2) print("a/2=",a/2) print("a**2=",a**2)...
Properties of complex numbers Identities with complex numbers Introduction Many of the math problems are modelled using equations. Alllinear equations(equations of the first degree) with real coefficients always have real solutions. However, this cannot be said about quadratic equations or equations of ...
Some examples of complex numbers are 5i, 2+7i, and 9.4i. Actually, real numbers can be considered a subset of complex numbers because a real number could be written as r + si, where r represents the real number and s represents the coefficient to the imaginary number. So, the real ...

The principle argument of complex numbers has values from -π < θ <π. Further, It is 0 < θ < π, if taken in the first two quadrants where the angle is measured with respect to the positive x-axis in the anticlockwise direction. And it is -π < θ < 0 in the third and four...
Complex numbers are written in the form,x + yj, wherexis the real part andyis the imaginary part. We can use thetype()function to know which class avariableor a value belongs to. Let's see an example, num1 =5print(num1,'is of type', type(num1)) ...
