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)

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).

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
