Game: Racetricies

Racetricies

Play the thrilling game that has taken the world by storm, it is bigger than the World Cup. Champion race-tricitarians from 52 different countries come to one place to fight to see who is the Race-tricies world champion.

Now this thrilling game is in the home, classroom, or where-ever you wish to perform the rituals of this amazing game!

Players: 3 + Players

How to play:

  1. Allocate roles, let one person be the neutral judge and the rest the players. WARNING: The judge will find it hard to resist joining in the game.
  2. The neutral judge must choose a systems of equations question: eg. 3x+2y-z=19, 4x-y+2z=4, 2x+4y-5z=32. Or if he wants to make the round challenging make one up.
  3. Start the timer and go. The players must now solve the equations using matricies.
  4. The winner of the game is the person who gets the correct answer first. Once your answer has be submitted you are not allowed to change your answer.

Variations:

  • Solve the equation in only 5 steps
  • Solve the equation only writing the new matricies and no other information

Game: Guess the value of cos

Guess the value of cos

Players: 1 to 1 billion

How to play:

This is a simple game that can be played at anytime, eg. on the bus, while driving, while on the phone, or when skydiving. The aim is simple, one must say to the players, or to themselves a randomly chosen angle in degrees (easiest), radians (getting harder) or gradients (challenging).

Once you have told all the players the angle, all must guess the value of the cosine of that angle.

The person with the closest value to the correct value is the winner! Or if you are by playing by yourself, go get a life.

Then choose if you want to play the game again.

Variations of the game:

Find the sine, tangent, squine, cosquine or squangent of an angle.

Notes: Polar Coordinates

Moving from Cartesian coordinates to polar, or vice versa

Where (x,y) and [r,θ]:

  • r = \sqrt{x^2+y^2}
  • \tan \theta = \frac{y}{x}
  • x = r \cos \theta
  • y = r \sin \theta

The distance between two points

Two Cartesian coordinates (x1,y1) and (x2,y2) is given by:

  • \sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2}

Two Polar Coordinates (r1, θ1) and (r2, θ2) is given by:

  • \sqrt{r_{1}^2+r_{2}^2 - 2 r_{1} r_{2} \cos (\theta_{1}-\theta_{2})}

Polar equations and graphs

r = constant

Equations of the form r = k have graphs that are circles, centre at the origin and radius k.

θ = constant

Equations of the form θ = k (and r ≥ 0) have graphs that are half lines, from the origin and making an angle k with the positive x-axis.

r = kθ

Equations of the form r = kθ have graphs that are Archimedes spirals.

Year 2 students given calculators

YEAR 2 students are learning to add up on calculators in a Cairns school.

The Cairns Post reports mother-of-four Fleur Nightingall was disgusted when her seven-year-old son Jayden’s teacher at Trinity Beach State School asked for him to be supplied with a calculator to learn maths for his year 2 classes next year.

“I just shook my head. I was stunned,” Mrs Nightingall said.

“My son is still learning how to do sums on paper, let alone getting a calculator. It’s disgusting – absolutely disgusting.”

Education Queensland maintains the calculators support students’ mathematics learning and does not detract from this focus.

Maths done on surviving a zombie attack!

A ZOMBIE attack would need to be countered hard and early to give civilisation any hope of surviving, according to a mathematical study.

A Canadian team – which includes an Australian researcher – has done the maths on what would happen should zombies really appear on the streets.

Modelling various outcomes, including what happens when quarantine is implemented or a cure found, the group found a failure to “hit hard and hit often” would be devastating.

Professor Robert Smith?* – an Australian now working at the University of Ottawa – told the Wall Street Journal that even finding a cure for zombie-ism left an unsatisfactory situation.

“Unless the cure was 100 per cent, which it would never be in reality, you can’t turn all the zombies back. (You achieve) this equilibrium where people are always switching back and forth.”

While the study may

Students’ stories of exam success

Tens of thousands of A-level students have been receiving the news that will change the course of their lives. Some high-flying students are celebrating outstanding results. And as they tell the BBC News website, they will remember today for the rest of their lives:

THE MATHS PRODIGY

Niall Thompson will leave home at the early age of 15 to study maths at Magdalene College, Cambridge.

Niall grew up in Mossley in Greater Manchester and will be the first person in his family to go to university. He was brought up by his mother, Bev.

Niall said: “She’s more excited than me really, she’s really chuffed. She was really pleased for me.

“It is just amazing. To know I have got proof that I have done enough is just amazing.”

Niall was educated at a state school and gained four A grades in maths, further maths, statistics and physics – as well as a distinction in the tough

Google uses math formulas to find employees that are most likely to quit

According to the Wall Street Journal, Google has developed a mathematical algorithm that will identify the employees that are most likely to quit becaue they feel that they are being under-used.

The American internet giant in charge of the second most used website on the internet, Google, has begun entering details of their 20,000 employees into a mathematical formula that will apparently be able to identify the employees that feel under-used and are likely to quit.

Google’s HR Chief in the US, Laszlo Bock,  says, that the algorithm will ‘get inside people’s heads even before they know they might leave’.

Advertising sales boss Tim Armstrong and display advertising chief David Rosenblatt have both quit their jobs recently and using this formula it should help lower the level of people quiting Google. Bosses at Google believe that people are quitting Google because the employees believe that they are not making as much of a difference
