Practice Your X-Ray and Time-Lapse Vision Calculus trains us to use X-Ray and Time-Lapse vision, such as re-arranging a circle into a "ring triangle" (diagram). This makes finding the area… well, if not exactly easy, much more manageable. But we were a little presumptuous. Must every circle in the universe be made from rings? Heck no! Now we're talking. Imagine each strategy unfolding over time, using your time-lapse vision. Graphing Calculator. IXL - Year 8 maths practice.

An Intuitive Guide to Linear Algebra – BetterExplained. Despite two linear algebra classes, my knowledge consisted of “Matrices, determinants, eigen something something”.

Why? Well, let’s try this course format: Name the course Linear Algebra but focus on things called matrices and vectorsTeach concepts like Row/Column order with mnemonics instead of explaining the reasoningFavor abstract examples (2d vectors! 3d vectors!) And avoid real-world topics until the final week The survivors are physicists, graphics programmers and other masochists. Linear algebra gives you mini-spreadsheets for your math equations. We can take a table of data (a matrix) and create updated tables from the original. Here’s the linear algebra introduction I wish I had, with a real-world stock market example.

What’s in a name? “Algebra” means, roughly, “relationships”. “Linear Algebra” means, roughly, “line-like relationships”. Straight lines are predictable. Lines are nice and predictable: Linear Operations An operation is a calculation based on some inputs. No! Ok. X y z. Understand Ratios with “Oomph” and “Often” – BetterExplained. Ratios summarize a scenario with a number, such as “income per day”.

Unfortunately, this hides the explanation for how the result came about. For example, look at two businesses: Annie’s Art Gallery sells a single, \$1000 piece every dayFrank’s Fish Emporium sells 250 trout at \$4/each every day By the numbers, they’re identical \$1000/day operations, right? Hah. Here’s how each business actually behaves: Transactions are the workhorse that drive income, but they’re lost in the dollars/day description. With Oomph and Often, I visualize two distinct levers to increase. Why make it difficult? Horsepower, Torque, RPM In physics, we define everyday concepts like “power” with a formal ratio: Ok.

Utilities - KCalc. KCalc is a calculator which offers many more mathematical functions than meet the eye on a first glance.

Please study the section on keyboard accelerators and modes in the handbook to learn more about the many functions available. The latest stable release is version 2.11, included in KDE SC 4.9. KCalc is a free and open source software, available for Linux and similar operating systems under the GNU General Public License (GPL), Version 2. In addition to the usual functionality offered by most scientific calculators, KCalc offers a number of features, which I think are worthwhile pointing out: KCalc provides trigonometric functions, logic operations, and it is able to do statistical calculations.

KBruch. Description KBruch is a small program to practice calculating with fractions.

Therefore 4 different exercises are offered. Exercise Fraction Task - in this exercise you have to solve a given fraction task. You have to enter numerator and denominator. This is the main exercise. KBruch provides a handbook describing the different exercises and the general usage. Desmos Graphing Calculator.

Magical Maths Toolkit. The “Magical Maths” Toolkit was set up in early 2007 to act as a learning hub for Maths teachers around the world.

The success of the Maths Toolkit led to the introduction of the highly acclaimed Educator Toolkit. The site receives thousands of unique visits per day, and has developed into a site where Maths teachers across the globe share resources to aid the development of OUTSTANDING teaching pedagogy. Make sure to comment and share any of the posts that you find useful or interesting. If you would like to be a guest blogger on the site and contribute to the toolkit then contact us.
