1. Multiply (0+i)(1+i) =
Graph your answer by changing from (a+bi) to (a, b).
2. Multiply (0+i)(2+i) =
Graph your answer by changing from (a+bi) to (a, b).
3. Multiply (0+i)(2+2i) =
Graph your answer by changing from (a+bi) to (a, b).
4. Connect the answer points to show how triangular region R has rotated 90 degrees.
5. Multiply each answer complex number point by (0+i) and graph.
6. Multiply each of those answers by (0+i) and graph.
7. What happens if you multiply by (0+i) a fourth time?
8. Multiply: A, B and C, each vertex point's complex number, by some complex number c = a+bi where a^2 + b^2 = 1 and graph your results on another graph page. Find the angle associated with this complex number c. Hint: If a is positive and b is positive then Tan(c's angle) = b/a or c's angle = ArcTan(b/a).
9. Multiply: A, B and C, each vertex point's complex number, by some complex number c = a+bi where a^2 + b^2 not = 1 and graph your results on another graph page. Find the angle associated with this complex number c. Find the magnitude of complex number c where magnitude of c = (a^2 + b^2)^(1/2).
10. Write a few comments giving your conclusions from problem 8 and 9.
