Ma.fi. Matteva. The Number System. Quadratic Factorisation: The Complete Guide. When it comes to quadratic polynomials — which seem to come in all shapes and forms — most of us have spent at least a semester just learning about how to maneuver around them.

Quadratic Factorisation: The Complete Guide

Indeed, when we look at a standard math curriculum on quadratic expressions, we would find topics such as square of a sum, square of a difference, completing the square, direct factoring, grouping, difference of squares. AC method (if you’re lucky) and quadratic formula — among others. In what follows though, we will — in addition to putting some of the aforementioned techniques into good use — develop a general technique for factorising any kind of quadratic polynomials. And yes — the same technique would apply to those with complex numbers as coefficients too! Review — Basic Factoring Techniques. Learn Higher Mathematics The Online Way. Ma3c Resurser.

5 Books for Math Teachers that will Change your Teaching - RETHINK Math Teacher

But finding the time to weed through them all, so that you know which ones will be the most benefit for you can be time consuming. So I have this list of 5 books for math teachers that will guide you through actionable steps to help improve your math teaching. All 5 books are extremely practical, and easy to begin implementing immediately. Equation Strips. In Ontario our grade 7 students are introduced to solving simple equations in the form ax + b = c where the values of a, b and c are whole numbers.

Equation Strips

We think it's a good idea for them to start by having some sort of visual representation of each equation. In this activity, students are given 16 cards that correspond to 16 equations represented as strips (the top and bottom of the strips represent the left and right sides of the equations). Students solve for x given the strips and then rewrite the algebraic form equation. Bar Model Basics. The "Model Method" is a teaching innovation developed in Singapore in the late 1980's.

Bar Model Basics

It was developed as a strategy to help students make sense of and solve word problems in the elementary grades. It is a useful strategy for modeling addition, subtraction, multiplication, division, ratios, fractions, percents, and even algebra.

Can you solve the prisoner hat riddle? - Alex Gendler. 7. - 10. klasse - Tivoli. The Mathematics of Juggling. The late computer scientist Claude Shannon has a well-deserved reputation as the father of information theory, but he was also an avid unicyclist, juggler and tinkerer.

The Mathematics of Juggling

He even built his own robotic juggling machine out of parts from an Erector set, programming it to juggle three metal balls by bouncing them against a drum. In the early 1980s, Shannon published the first formal mathematical theorem of juggling, correlating the length of time balls are in the air with how long each ball stays in the juggler’s hand. His theorem demonstrated the importance of hand speed to successful juggling. Mathematicians have been fascinated by juggling ever since.

“I think it’s a matter of making sense of the order that’s in the juggling patterns,” said Jonathan Stadler, a math professor at Capital University in Ohio who started juggling as a teenager. AP CALCULUS RESOURCES !!! - GeoGebraBook. Consider the function . What happens as the input (x) gets bigger and bigger? The exponent will get infinitely large, but the base, , will approach the value 1 because as x gets bigger (i.e. "approaches infinity"), the ratio approaches zero.

Thus, as x approaches infinity, we have a limit that structurally looks like 1^("infinity"). Five Principles of Extraordinary Math Teaching. The Quadratic Formula - INTUITIVE Derivation. Super Maths World. The Seven Sins of Statistical Misinterpretation. Statistics is a useful tool for understanding the patterns in the world around us.

But our intuition often lets us down when it comes to interpreting those patterns. In this series we look at some of the common mistakes we make and how to avoid them when thinking about statistics, probability and risk. 1.
