Follow hints to investigate the matrix which gives a reflection of the plane in the line y=tanx. Show that the combination of two reflections in intersecting lines is a rotation.
Follow hints using a little coordinate geometry, plane geometry and trig to see how matrices are used to work on transformations of the plane.
In a snooker game the brown ball was on the lip of the pocket but it could not be hit directly as the black ball was in the way. How could it be potted by playing the white ball off a cushion?
Some local pupils lost a geometric opportunity recently as they surveyed the cars in the car park. Did you know that car tyres, and the wheels that they on, are a rich source of geometry?
Patterns that repeat in a line are strangely interesting. How many types are there and how do you tell one type from another?

A shape and space game for 2,3 or 4 players. Be the last person to be able to place a pentomino piece on the playing board. Play with card, or on the computer.
What are the coordinates of this shape after it has been transformed in the ways described? Compare these with the original coordinates. What do you notice about the numbers?
The centre of the larger circle is at the midpoint of one side of an equilateral triangle and the circle touches the other two sides of the triangle. A smaller circle touches the larger circle and....Develop and price individual life participating products, including assumption review, profitability analysis and system implementation.

Until now, and this. This is the Agera, the latest hypercar from everyone's favourite mad Swedes.
Though Koenigsegg would love you to believe so, it isn't quite all-new, but instead a heavily modified, powered-up and angrified version of the outgoing CCX.
The Agera puts out - get ready - a deranged 898bhp from a 4.7-litre V8. Add in a not-immodest 811lb ft of torque and you're looking at a thing that can dispatch 62mph in 3.1 seconds and 124mph in under nine seconds before topping out at something very close to 250mph. Those are mad, mad numbers.
But our favourite number is a slightly more subtle one: 72kg. That's how much the Agera's entire carbon fibre chassis weighs, which is less than many normal-sized humans - most of whom are not, admittedly, made of carbon fibre.
The Agera gets adjustable suspension, a removable hard-top and bodywork rendered entirely in carbon fibre and Kevlar. Thanks to its flat underbody and many clever wings, it produces over 300kg of downforce at 155mph.
How much will it cost? Er, lots. We can't imagine that'll get in the way of Koenigsegg's desire to sell around 20 Ageras each year, though.
They say their order books are open right now at the Geneva show. Better get your man to put in a phone call quicksharp if you want one of these hypercars.
Actually, we're pretty sure Koenigseggs have just smashed right out the top end of the ‘hypercar' description. We need a new word.
Ultracars? Megacars? Suggestions please...

What do you think?Learning how to use HTML, CSS and the basics of JavaScript can be fairly simple. Almost anyone can produce a small, functional website providing you know how to use Google and have some patience.
However, if you bump the scale of that website up about 10x, add in another developer and create multiple variants – each with their own unique functionality and styles – your code is going to become a hassle to maintain and new hires are going to have a nightmare trying to figure out your codebase.
Writing more maintainable code is just the first step. Get the ultimate guide to JavaScript error monitoring here.
Using a CSS preprocessor like Sass (Syntactically awesome style sheets) effectively will help modularize your CSS code making it more maintainable, understandable and reusable. Sass consists of two syntaxes, the original syntax called “the indented syntax” and the newer “SCSS”. The examples I give in this post use the SCSS syntax as this is my personal preference,
