Since a sinusoidal waveform is really based off of a rotating circle you can describe its position in time using polar coordinates (magnitude, phase angle) OR put that circle on a Cartesian plane and describe it with normal x and y coordinates (instead of x and y we call it real and imaginary because the sinusoids we see are really just the up and down parts, aka 1 of the 2 dimensions, of the entire rotating circle).

How do you write a pseudocode for additing two complex number?

Real part of the result = real part of first number + real part of second number Imaginary part of the result = imaginary part of first number + imaginary part of second number


Are imaginary and complex numbers the same?

No. A complex number is a number that has both a real part and an imaginary part. Technically, a pure imaginary number ... which has no real part ... is not a complex number.


Is every complex nberan imaginary number?

No. A complex number consists of a real part and a imaginary part. If the real part equals zero, there is only the imaginary left and you could therefor argue that it is an imaginary number (or else it would still be a complex number -with a real part=0)


Is 5192716162 a real number?

Real numbers are the subset of complex numbers with the property that their imaginary part is zero. Since the above number has no imaginary part, it is a real number.


How can you tell which part of a complex number is the real part and which is the imaginary part?

The imaginary part is expressed as a product of i(square root of negative one), typically following a plus sign, so that the complex number has the form a + bi, with "a" the real part and "bi" the imaginary part.


A complex number might not be a pure imaginary number?

True. Complex numbers have a real part and an imaginary part. If either one of these is zero, the complex number will be a pure real or a pure imaginary.


What is the square root of -34?

Square roots of negative numbers are complex, meaning that they carry a 'real' and an 'imaginary' part. Here the real part is approximately 5.8309518948453 and the imaginary part is i.


Can a number be both complex and imaginary?

A complex number has a real part and a (purely) imaginary part, So imaginary numbers are a subset of complex numbers. But the converse is not true. A real number is also a member of the complex domain but it is not an imaginary number.


How do you find the additive inverse of a complex number?

You take the additive invers of the real and of the imaginary part. For instance, the additive inverse of: (3 - 5i) is (-3 + 5i).You take the additive invers of the real and of the imaginary part.

How do you write complex numbers in the form a plus bi?

A complex number comes in two parts: a real part and an imaginary part. If the value of the real part is a and the value of the imaginary part is b, the number is written as a + bi.


What are the characteristics of a complex number?

A complex number must have a real and imaginary part. It can be in the form: a + bi i is an imaginary number and a and b are real numbers


Fomular for complex numbers?

A complex number is a number with a real part and an imaginary part. It is written in the form a+bi. a is the real part & bi is the imaginary part. Recall that i = square root of -1. An example would be 2+3i.
