## Trigonometry

In Maths recently, I have been teaching myself and others the fundamentals of Trigonometry (Sine, Cosine, Tangent) and about The Law of Cosines. Unfortunately, though it is not that hard, whenever I've used to try to solve for a side of a triangle, I've ended up with a ridiculously far out answer. Even when I've tried with other people it's always turned out badly, but I've kept on trying.

A rough guide to some Mathsy Stuff:
Sine =
Opposite
Divided
Hypotenuse

Cosine =
Divided
Hypotenuse

Tangent =
Opposite
Divided

Opposite: The side opposite the Thete
Hypotenuse: The longest side
a: A side that isn't the Hypotenuse
b: The other side that isn't the Hypotenuse
c: The Hypotenuse
A, B, C: The angle opposite the side with it's lower case counterpart

Law of Cosines: (a squared) + (b squared) - 2ab*cos*C = c

## Digitally Altering Photos

A few weeks ago during TIG (Technology, Informational Studies, Guidance), we learnt about the affects of digitally altering photos, and afterwards we had to answer some questions on the subject. Here are the questions and my subsequent answers:

What does it mean to alter a photo?
To digitally change a photo so it is different from the original.

What are some pros/cons of doing so?
It can help to sell a product and for advertising, but it can also make people want to look like something or someone in a way that can't naturally be acheived.

Why do magazines alter photos?
To increase the amount of products bought, and to boost advertising.

What would you teach others about digitally altering and altered photos?
Don't buy things advertised by magazines, as you almost always won't get the same/desired result.

## A Selection of Passages From "The Long Dark Tea-Time of the Soul"

Here are a selection of passages from the book; "The Long Dark Tea-Time of the Soul":

Chapter 1, Page 1:
It can hardly be a coincidence that no language on Earth has ever produced the expression “as pretty as an airport”.
Airports are ugly. Some are very ugly. Some attain a degree of ugliness that can only be a result of a special effort. This ugliness arises because airports are full of people who are tired, cross, and have just discovered that their luggage has landed in Murmansk (Murmansk airport is the only known exception to this otherwise infallible rule), and architects have on the whole tried to reflect this in their designs.

Chapter 1, Page 2:
All the way out of London to Heathrow she had suffered from doubt. She was not a superstitious person, or even a religious person, she was simply someone who was not at all sure she should be flying to Norway. But she was finding it increasingly easy to believe that God, if there was a God, and if it was remotely possible that any godlike being who could order the disposition of particles at the creation of the Universe would also be interested in directing traffic on the M4, did not want her to fly to Norway either. All the trouble with the tickets, finding a next-door neighbour to look after the cat, then finding the cat so it could be looked after by the next-door neighbour, the sudden leak in the roof, the missing wallet, the weather, the unexpected death of the next-door neighbour, the pregnancy of the cat - it all had the semblance of an orchestrated campaign if obstruction which had begun to assume godlike proportions.

Chapter 1, Page 4:
Jean-Philippe was, as the taxi-driver correctly guessed, the reason why she was going to Norway, but was also the reason she was convinced that Norway was not at all a good place for her to go. Thinking of him made her head oscillate and it seemed best not to think about him at all and simply go to Norway as if that was where she happened to be going anyway. She would then be terribly surprised to bump into him at whatever hotel it was he had written on the card that was tucked into the side pocket of her handbag.

### Data Handling

Recently in Maths we have been learning about data handling. We learned about surveys and graphs and how to make them, so here are some 4 steps to making a survey ad using your data:
1. First, come up with some questions that you want to ask people.
3. Show your data in the form of a graph or something similar
4. Finally, use your data for whatever purpose you needed the data for in the first place
However in data handling doesn't only involve surveys and graphs, it also involves things like the mean, median and mode. "What are they?" you ask.
Well, lets start with the mean. The mean, also known as the average is the average amount in a set of numbers. You find the mean by adding up all of your numbers and then diving the sum by the number of numbers you've added together, for example, if you had the numbers 5, 6, 7, 3, 5 and 10 then the mean would be 6.
Next thing, the median is the center value, or number in the middle of a set of numbers put in consecutive order. So really, all you need to do to find the median is to put the numbers in order and find the number in the middle. In the sequence 5, 8, 9, 10, 16, then the median is 9 because its the number in the middle.
Lastly, there's the mode. The mode is probably the easiest one of these to find explain, and it is just the most recurring number in a series.

## PYPX This Week

This week, I have been working PYP Exhibition. Our group is focused on giving others a sustainable food source and have arranged talks with all sorts of people to learn how to do so; Chef Adam, the Gardener (David Buckner) and continuing talks with our mentor, Ms Deborah (the MSHS librarian). So far, we don't have any definitive plan, but we have a main idea that we will continue to work on. I think my group did well, but we need to focus on our work and argue less.
