This example visualizes the complex roots of polynomials. Key mathematical concepts include complex numbers and polynomials. Using GeoGebra commands such as If, Sequence, and Textfield, the complex roots of polynomials are constructed. Suitable for high school mathematics education and learning.

GeoGebra Commands & Parameters

  1. If(a ≠ 0, myFA, If[b ≠ 0, myFB, If[c ≠ 0, myFC, If[d ≠ 0, myFD, If[e ≠ 0, myFE, If[e ≠ 0, myFE, myFG]]]]]) → fx
  2. Sequence(x = x(Element[myTPsA, k]), k, 1, Length[myTPsA]) → vTPLinesA
  3. Sequence(x = x(Element[myTPsA, k]), k, 1, Length[myTPsA]) → Lines2
  4. Textfield(a) → inputBox1
  5. Textfield(b) → inputBox2
  6. Textfield(c) → inputBox3
  7. Textfield(d) → inputBox4
  8. Textfield(e) → inputBox5
  9. Textfield(g) → inputBox6
