Are Imaginary Numbers Really Imaginary? 1.Open a word document and explain in your own words what an imaginary number is. The explanation should be clear enough that anyone reading it would understand. 2.Explain the difference between the definition of imaginary that we have used to describe things that really don’t exist and the definition of imaginary as it applies to imaginary numbers. 3.List the progression of the powers of i. 4.List the rules for addition, subtraction, and multiplication of complex numbers. Include an example of each. 5.Explain what a conjugate is and their use in dividing complex numbers. 6.Save your document as firstname_lastname_hour on the h drive. Explain what an imaginary number is. This task uses: Learning Objective(s): Define imaginary number Explain the definition List the powers of i S SUBSTITUTION Technology acts a direct substitute, with no functional improvement

Writing an Equation with Real or Imaginary Roots 1.Within your group, write 2 quadratic equations. One of these equations should have real roots and one should have imaginary roots. 2.You will graph each of these equations in desmos to verify that it has the intended root (real or imaginary). a. Go to and click on the icon in the upper left hand corner and select f(x) expression. b. Enter your equation. c. Click on the icon to set the correct viewing window. 3.Return to Stoodle and enter your equations. 4.Look at the equations that the other groups have entered, and answer the following question: 3.How can you tell what type of roots a quadratic equation will have without graphing the equation? You will write and graph 2 equations; one with real and one with imaginary roots. This task uses: Learning Objective(s): Write equations with real or imaginary roots. Discuss other ways to determine whether an equation has real or imaginary roots. R REDEFINITION Technology allows for the creation of new tasks that were previously not conceivable.
