COMPLEX QUIZ ON THURSDAY, SEPT. 28TH Active Learning Assignment? Answers to “Powers of i” assignment”: COMPLEX QUIZ ON THURSDAY, SEPT. 28TH Worksheets

LESSON: To graph in the complex plane: For (a + bi), the x axis is the real part (a) and the y axis is the imaginary part (bi). Graph: 7 + 8i bi Graph: -5 + 9i a What are these?

What is the resultant vector? Find the sum of 6 – 2i and - 4 – 3i, graph both the complex numbers and their resultant. (Use the parallelogram rule) bi (6 – 2i) + (-4 – 3i) 6 – 2i + -4 – 3i = 2 – 5i 6 – 2i a -4 – 3i Algebraic representation Graphical representation 2 – 5i What is the resultant vector?

Find the sum of 5 + 2i and -6 + 4i, graph both the complex numbers and their resultant. (Use the parallelogram rule) bi a 5 + -6 + 2i + 4i = -1 + 6i -1 + 6i How to graph just 3i? (It’s really 0 + 3i) -6 + 4i How to graph just -4? 5 + 2i (It’s really -4 + 0i) How to graph just 4 – 3i ? (It’s really 4 – (3 * )i (Use the calculator!) (How about 4 – 6.7i ?)

COMPLEX QUIZ ON THURSDAY, SEPT. 28TH Active Learning Assignment: H/O for AM2.3b #1 – 20, Col. 1, 2 (For 11 – 20, Give both the Algebraic and Graphical representations and use the parallelogram rule) COMPLEX QUIZ ON THURSDAY, SEPT. 28TH WOW: Choose your life’s mate carefully. From this one decision will come 90% of all of your happiness or misery.
