AI Drawing Prompt Reference

Create a dynamic illustration of the relationship between complex numbers and vectors, showing the geometric meaning of complex numbers and vector operations. First, generate a random real number a between 2 and 5, then generate a random real number b between 1 and 2, and another random real number c between -3 and -6. Use a and b to create a polynomial function f, and use c to create another polynomial g. Dynamically show the addition of complex numbers, vector addition, and the relationship with trigonometric functions using these random numbers and polynomials.
