I keep getting “Argand plane” questions wrong in Complex Numbers. What's the trap?
plotting the imaginary part on the x-axis.
The usual trap: plotting the imaginary part on the x-axis. How to avoid it: real part → x-axis, imaginary part → y-axis. Go back to the definition — a complex number a+bi is a point (a, b), turning algebra into geometry.
Key point
Argand plane
Common mistake
plotting the imaginary part on the x-axis.
Memory tip
real part → x-axis, imaginary part → y-axis.
