i is the representation of SQRT(-1) and is the variable that is used with imaginary numbers.

'; explain[1] = '#2

i is defined as the SQRT(-1).

'; explain[2] = '#3

Complex numbers are defined to be numbers including imaginary and real numbers.

'; explain[3] = '#4

Imaginary numbers are possible to graph, but not within the real coordinate axis, you must use the imaginary coordinate plane.

'; explain[4] = '#5

Graphing imaginary numbers requires an imaginary coordinate plane. In order to tell the difference between the real and imaginary coordinate plane, the axis are labeled as x and y in real, and real and imaginary in imaginary.
