Eulers identity fun year 10 lesson

Eulers identity fun year 10 lesson

A fun end of term lesson I used with my top set year 10s (after they bugged me to teach them about complex numbers for eons). I wouldn’t necessarily suggest this for anyone other than very capable, extremely engaged mathematicians…

Multiplying Complex Numbers – Math puzzle

Multiplying Complex Numbers – Math puzzle

Multiplying Complex Numbers – Math puzzle Use conjugates to rationalize a denominator. I’ve included three different sizes of the same puzzle. The smaller size is only two pages and is great if you are going to print of individual (or to work in pairs) copies for students to practice in class or at home. The larger size requires 3 pieces of paper and quite a bit of space to solve – fun for centers and group work. The extra-large size requires 8 pieces of paper. Cut out the puzzle pieces (or even better if your students do it themselves) and students are to solve the puzzle so that it matches the solution provided. If your students are going to cut out the pieces then no prep is needed – the puzzle is not in order. I’ve been using these puzzles for years with great success! I recommend printing the puzzles on colourful paper and laminating them. This way you only have to cut them out once and they will last for years! What is included in this product? • The solution to the puzzle – Page 3 • The normal size puzzle – Pages 4 – 5 • The large size puzzle – Pages 6 – 8 • The extra-large size puzzle – Pages 9 – 16 • Questions and Answers in a table format for easy grading or you can cut these out to play a matching game – Pages 17 – 19 My students love doing these types of puzzles. This product can also be used as a perfect revision of the school work to do at home. All answers can be easily checked thanks to the included solution to the puzzle or questions and answers shown in a table. Thank you for checking my resources.

40 slide Powerpoint Advanced Higher Maths Complex Numbers Argand Diagrams Worked Solutions

40 slide Powerpoint Advanced Higher Maths Complex Numbers Argand Diagrams Worked Solutions

40 slide Powerpoint for Advanced Higher Maths Unit 2: Complex Numbers. There is a brief revision of the basics of Complex numbers followed by a series of questions. The 24 questions (many of them multi-part) require the construction of Argand Diagrams, use of the quadratic formula, polynomial long division, and simultaneous equations. There are fully worked solutions (including diagrams) for complex number topics relating to: Equating Real and Imaginary Parts; Finding square, cube, fourth, fifth and sixth roots of complex numbers (including unity) and plotting them on an Argand diagram; Verifying and finding roots of complex number polynomials; Expanding and simplifying complex numbers using the Binomial Theorem and De Moivre’s Theorem; Interpreting geometrically loci in the complex plane; Conversions between polar and rectangular forms; Complex Conjugates; Exponential Form; Trigonometric identities, substitutions and simplification. The questions are grouped in approximate order of difficulty and to match the usual order of progress through this topic. *Animated workings come up line by line on mouse clicks.*

Euler's prime number Generator and 163

Euler's prime number Generator and 163

Presentation showing the solution of Euler's quadratic formula for generating primes and noting its irrational imaginary part of its complex solutions. When Euler's number, e is then taken to the power of pi*square root of 163 one mysteriously ends up with almost an integer-shown in wolfram. Link then to numberphile video that takes a different broader angle.

Mathematical Ambiguity & topic relationships

Mathematical Ambiguity & topic relationships

A presentation exploring ambiguity in the operations and objects of Maths and a set of concept maps that connect various topics of GCSE and IB/A level syllabuses. Quadratic, Log, Trigonometric and Functions are mapped in detail. Useful crossover introductory material that can provide some meaning and context in helping to make some connections between otherwise disparate fields. The presentation develops five areas in which the terms and processes of mathematics are inherently ambiguous: from the irrationals and infinity, the variable as a receptacle, the filling of the number line, forming operations with numbers to the notion of equality and sameness. That is from a number being both a noun (a fractional object) and a verb (process of adding a convergent series of rationals). That algebraic formulations using a variable x, allow for x in one sense to have any value ( before the equation is solved) to a specific value when it has been solved. As five separate chapters each one can serve as nonstandard provocative discussion/starter/plenary material .

Hilbert's Grand Hotel

Hilbert's Grand Hotel

Enrichment lesson. Mr Hilbert and his wife own an unusual hotel: it has an infinite number of rooms! Every room is full, but then Mr Two turns up … I wrote these two worksheets for year 7’s, who loved it, but anyone up to Further Mathematicians would be excited by mathematician David Hilbert’s very accessible metaphor for countable infinity. Youtube clip (not mine) is a great introduction. Excel sheet is to record thinking. Using names Mr 1, Mr 2, ... and Miss 1, Miss 2,... for guests helps clarify thoughts. Wikipedia article gives explanation and answers if you've never met this before!
