AI Drawing Prompt Reference

Draw the geometric representation of complex number multiplication. Start by taking point C on the y-axis, then draw line segments a and b from C to w and Z respectively. Next, take point D on the x-axis and draw line segment c from D to C. Calculate angle α (D, C, w) and angle β (D, C, Z). Finally, draw line segment d from C to E and calculate angle γ (D, C, E).
