Which is the correct notation for the complex number 113-square root-68?
113-2i sqr 17
What is the real part of the complex number -2i?
Ah, what a lovely question! When we have a complex number like -2i, we can see that the real part is 0. You see, the real part is the coefficient of the term with the variable "i," and in this case, there isn't a real part, so it's simply 0. Just a happy little zero floating peacefully in the complex plane.
When the sum of the complex numbers 3 plus 2I and 6 - 4I is graphed in which quadrant does it lie?
3+2i + 6-4i = 9-2i The real part of this number is positive, therefore it lies in Q1 or Q4. The imaginary part is negative, therefore it is in Q3 or Q4. Q4 is the common possibility, therefore 9-2i is in Q4.
Examples of complex numbers?
5+6i , -2-2i , 100+i.A complex number consists of a real part and an imaginary part: a+bi where 'i' is the imaginary unit (sq.rt(-1)).
Which of these are complex numbers 5 3i 1 2i?
All of them. Real numbers are a subset of complex numbers.
