Question 63489: When we draw the complex number i as a point in the complex plane, its coordinates are
a. (0, i )
b. (1,0)
c. (0,1)
d. The number i cannot be drawn as a point in the complex plane
When we add the two complex numbers a + bi and c + di by representing them as points in the complex plane, then the sum is represented by
a. The corner of a rectangle whose other three corners are (0,0), (a,b), and (c,d)
b. The corner of a triangle whose other two corners are (a,b) and (c,d)
c. the corner of a parallelogram whose other three corners are (0,0), (a,b), and (c,d)
d. None of the above
Just like we do for the real numbers, we can draw a picture of the complex numbers simply by drawing a line.
a. True
b. False
The Division Algorithm for Polynomials and the Factor Theorem for Polynomials (which we proved when the polynomials have real number coefficients) are both TRUE even if the coefficients of the polynomials come from the complex numbers.
a True
b. False

You can put this solution on YOUR website! When we draw the complex number i as a point in the complex plane, its coordinates are
a. (0, i )
b. (1,0)
c. (0,1)
d. The number i cannot be drawn as a point in the complex plane
Ans: (0,1) because the verticle axis becomes the imaginary part of the
comples number 0+1i.

d. None of the above
Ans: the corner of a parallelogram etc.......

a. True
b. False
Ans: False ; you need a plane with a Real number line as horizontal axis
and imaginary numbers as the vertical axis.
