WebComplex arithmetic. When we add complex numbers, we can visualize the addition as a shift, or translation, of a point in the complex plane. Example. Visualize the addition 3−4i 3 − 4 i and −1+5i − 1 + 5 i. The initial point is 3−4i 3 − 4 i. When we add −1+3i − 1 + 3 i, we add −1 − 1 to the real part, moving the point 1 units ... WebYes, π is a complex number. It has a real part of π and an imaginary part of 0. The letter i used to represent the imaginary unit is not a variable because its value is not prone to change. It is fixed in the complex plane at coordinates (0,1). However, there are other symbols that can be used to represent the imaginary unit.

Web2 days ago · Polar coordinates give an alternative way to represent a complex number.
