Question 13: (1 point} Express the following product of complex numbers in Cartesian form {1 + M: (2+)(7+2) = You must use lowercase i to represent the imaginary unit. llliluestion 1b: [1 point} Express the follmliring ratio of complex numbers in Cartesian form a. + bi: 2+2 5+ _ You must use lowercase 1'. to represent the imaginary unit. Question 1c: [6 points} For the complex number 2: = 11 + ti ii , nd the following quantities: mm= Imt' 2:] = 2': 2 [enter in Cartesian form a. + bi using lowercase 1' for the imaginary unit} 2:5 = (enter the exact answer using 1whole numbers or fractions} |z| = (in decimal form oorrect to 2 decimal places} Argfz) = (in decimal form oorrect to 2 decimal places} For the modulus and argument, it is helpful to rst sketch the complex number in the Argand plane and mark the angle that represents the argument. You can check your wort: by converting the polar form 2: = r'fcos' + taint?) back to Cartesian form.
