![]() ![]() This Complex Numbers & the Mandelbrot Set activity is designed to supplement MathLight's "Complex Numbers" Lesson in Unit 5: Quadratics. Early finishing students who need a challenge (that isn't busy work).An entire classroom of Algebra 2 students.Introduction and Answer Key videos accompany the activity so you have the flexibility to use this with: Work is checked via the teacher-provided Answer key or the Answer Key Video.Students extend their learning and develop their writing skills with Application section.Students complete the Exploration section of the activity: analyzing four different complex numbers to determine if they belong to the Mandelbrot Set.Use the included Introduction Video to provide background information in the activity's Understanding page.How can it be determined if a complex number belongs to the Mandelbrot Set?.In this activity, your students will answer this essential question: MathWorld-A Wolfram Web Resource.Thanks for checking out this Algebra 2 Activity on the topic of Complex Numbers! This activity will allow you and your students to investigate complex numbers and figure out what this Mandelbrot Set is all about.

The plots on the bottom have replaced with and are sometimes called " mandelbar The above figures show the fractalsģ, and 4 (Dickau). Generalizations of the Mandelbrot set can be constructed by replacing with or, where is a positive integerĭenotes the complex conjugate of. Set of completely different-looking images. So, for example, in the above set, picking inside the unit disk but outside the red basins gives a Note that completelyĭifferent sets (that are not Mandelbrot sets) can be obtained for choices of that do not lie in the fractal attractor. , and is allowed to vary in the complex plane. The term Mandelbrot set can also be applied to generalizations of "the" Mandelbrot set in which the function is replaced by some other function. Illustrated above, and approach the Mandelbrot set as the count Set lemniscates grow increasingly convoluted with higher count, The boundary between successive countsĬurves" Peitgen and Saupe 1988) defined by iterating the quadratic recurrence, A common choice is to define an integerĬalled the count to be the largest such that, where can be conveniently taken as, and to color points of different countĭifferent colors. Beautiful computer-generated plots can be then be created byĬoloring nonmember points depending on how quickly they diverge to. To visualize the Mandelbrot set, the limit at which points are assumed to have escaped can be approximated by The estimate of Ewing and Schober (1992). With 95% confidence (Mitchell 2001), both of which are significantly smaller than A zoom into the Mandelbrot Set, from 1:1 scale to a 6th-level mini-set. The area of the set obtained by pixel counting is (OEIS A098403 Its also from 2006 and might be older than you. ![]() This calculation also provided the limit and led the authors to believe that the true values Ewing and Schober (1992) computed the first values of, found that in this range, and conjectured that this inequalityĪlways holds. Furthermore, the sum converges very slowly, so terms are needed to get the first two digits, and terms are needed to get threeĭigits. ![]() These coefficients can be computed recursively, but a closed form is not known. ![]()
