2016年12月11日 · The graph of the complex number 3 i is at the coordinates (0, 3) on the complex plane. This means it is located on the imaginary axis, 3 units above the origin. Thus, the graph represents a single point in the complex plane located at (0, 3).

How to graph. Type your complex function into the f(z) input box, making sure to include the input variable z. Then hit the Graph button and watch my program graph your function in the complex plane!

To represent a complex number such as \(3i\) as a vector, we start at the origin \((0, 0)\) and draw an arrow pointing to its corresponding point \((a, b)\). For \(3i\), this simply involves drawing a line from the origin straight upward to the point \((0, 3)\).
