The modulus is 5sqrt2
It lies in quadrant 4
That 5 is a factor.
When adding and subtracting complex numbers, you can treat the "i" as any variable. For example, 5i + 3i = 8i, 5i -3i = 2i, etc.; (2 + 5i) - (3 - 3i) = (2 - 3) + (5 + 3)i = -1 + 8i.
Polar form = re^i(angle) r=(4+4)^.5 angle=atan(2/2) PF = (8)^.5*e^atan(1) pf = 2.83e^.7854i
Yes, a complex number can be graphed on a two-dimensional plane known as the complex plane. The real part of the complex number corresponds to the x-axis, while the imaginary part corresponds to the y-axis. The complex number is represented by a point in the complex plane, with its coordinates being the real and imaginary parts. The distance of the point from the origin represents the magnitude of the complex number.
