What is the complex number of its distance for the origin in the complex plane?
This is called the magnitude. It can be found (for a complex number a + bi) as:(where a & b are both real numbers and i is the imaginary unit)sqrt(a^2 + b^2)
What is the order of magnitude of the number of birthdays you have had?
Tens.
Is negative one third an irrational number?
No. A rational number is any number whose magnitude is the ratio of whole numbers.The magnitude of (one third) is the ratio ( 1 / 3 ).
What is the order of magnitude of the number 7985345?
6
Is the square root of 1 an irrational number?
No. An irrational number is still a real number - it lives on the number line.The square root of -1 (known as i) is an imaginary number. It is on the imaginary axis of the complex plane.A number with components from the real axis and the imaginary axis is a complex number, and is on the complex plane.
What is another name for absolute value of a complex number?
The absolute value of a complex number is the magnitude of the number, which is found from sqrt(a² + b²) for the complex number a + bi
How do you convret polar form of complex number into algebraic form?
For a complex number in polar form with Magnitude, and Angle: (Magnitude)*(cos(angle) + i*sin(angle)) will give the form: a + bi
What is the magnitude of the complex number 8 plus 2i?
8.2462 (rounded)
Why can not a complex number lesser or greater than another complex number?
Because a complex number is a two dimensional entity. The concept of less than or greater than, for ordinary numbers, is one-dimensional. It can be applied to the magnitude (absolute value) of a complex number.
What is the complex number of its distance for the origin in the complex plane?
This is called the magnitude. It can be found (for a complex number a + bi) as:(where a & b are both real numbers and i is the imaginary unit)sqrt(a^2 + b^2)
What is triangular inequality of complex number?
The absolute value of the sum of two complex numbers is less than or equal to the sum of their absolute values.
How can you reconstruct a complex number given the amplitude and phase?
A complex number of the form M /_ÆŸ (Magnitude and angle ÆŸ), can be converted to the format {a + bi} as follows: M*(cosÆŸ + isinÆŸ)
Define conjugate number?
A conjugate number refers to a complex number having both the imaginary and real parts of opposite signs and equal magnitude.
Is 12 times a Complex Number greater than 5 times the same complex Number?
Although the magnitude of 12 times a complex number will be greater than 5 times the same complex number, complex numbers are not ordered in the same way that ordinary numbers are. So you cannot compare 12*(x+iy) and 5*(x+iy).
when a complex number z is written in its polar form, z = r (cos(theta) + i * sin(theta)), the nonnegative number r is called the or modulus, or z?
Magnitude
Write a function to-complex that accepts two input arguments containing the magnitude mag and angle theta of the complex number in degrees and returns the complex number c?
complex to-complex(mag, theta) { if(mag >=0) { real = mag * cos(theta); img = mag * sin(theta); return real + i * img; } else raise error; } One test is needed : mag must be a positive number! And the return value is depending of your way to deal with complex number
