Lesson Plan

Can You Hear Me Now? Using Cell Phone Signals to Divide Complex Numbers:

Students always ask, “What’s the point of complex numbers?” One application of complex numbers is cell phone signals and their wavelengths. This lesson introduces division of complex numbers by hooking students in with the topic of cell phones. Students will attempt to calculate a cell phone signal wavelength involving complex numbers and discover the use of complex conjugates. Then, students will practice with complex number division using a pairing strategy. To conclude, students will use white boards and dry erase markers to review the concepts covered in class.
