AI Drawing Prompt Reference

Draw a dynamic geometric diagram to demonstrate complex number addition and multiplication, including a quadrilateral representing the complex plane, two vectors representing complex numbers, a unit circle, and two new quadrilaterals obtained through vector addition and multiplication operations, showing the geometric meaning of complex numbers. Start by drawing the quadrilaterals and vectors representing complex numbers, then obtain new complex numbers through vector operations, draw the new quadrilaterals representing these complex numbers, and finally display the results of addition and multiplication.
