The following quesitions regard complex numbers, thank you so much for helping.
What are the coordinates of the complex number, i?
When we add the two complex numbers a + bi and c + di by representing them as points in the complex plane, how would you express the sum?
What is the absolute value of: -5 + 3i?
What is the absolute value of: 3 - 2i
Every complex number of the form a+bi can be seen as an ordered point (a,b) on the complex plane. For i, a=0, and b =1, so it is the point (0,1). Adding coordinates is exactly how it works in the normal coordinate plane.
Absolute values of a complex number $\displaystyle a+bi = \sqrt(a^2+b^2)$
no doubt your explanasion is correct, but you must of gathered that my math is quite week otherwise i wouldnt of joined this forum. I still dont really understand the second question i asked. Where you said when adding its just the same as standard coordinateds.
What is the absolute value of: -5 + 3i? Would this be 8?
What is the absolute value of: 3 - 2i Would this be 5?
