About me

ABOUT ME

I am an Economics student at Durham University who took Maths, History, Economics and Further Maths for A Level. I am very enthusiastic abotu the subjects I took, particularly Economics (obviously or I wouldn't still be doing it :) )

THE SESSIONS

For Maths, I am most familair with OCR but am able to tutor any exam board.

For Economics, I am familair with AQA but given the changes to A Levels I am again able to tutor to any exam board.

For History, I am familair with Pre-U but can do any A Level syllabus. However, I would only be comfortable in one of the following topics:

 - source based questions

 - America 1760 - 1860

 - Russia 1820 - 1880 or 1905 - 1924

 - Germany 1815 - 1890

  -France 1815 - 1870

 - Italy 1815 - 1870

Differentiate y = 4ln(x)x^2

So we want to differentiate y =  4x2ln(x) with respect to y. For this we need to use the product rule. The product rule is D {f(x)g(x)} = f(x)g'(x) + g'(x)f(x) We can therefore make f(x) = 4x2 and g(x) = ln (x) f'(x) = 8x nad g'(x) = 1/x Therefore dy/dx = 8xln(x) + 4x2/x which can be simplie...

So we want to differentiate y =  4x2ln(x) with respect to y. For this we need to use the product rule.

The product rule is D {f(x)g(x)} = f(x)g'(x) + g'(x)f(x)

We can therefore make f(x) = 4xand g(x) = ln (x)

f'(x) = 8x nad g'(x) = 1/x

Therefore dy/dx = 8xln(x) + 4x2/x which can be simpliefied to 8xln(x) + 4x, which can be further simplified to get the answer:

4x(2ln(x) + 1)

Explain the main sources of monopoly power.

 - Barriers to entry, for example patents, restrict the number of competitors in a market. They may be deliberate, e.g. patents, or inherent in the good, e.g. water. Where they are inehrent, a 'natural monopoly' occurs. Monopolies may be a single firm in the market or created through collusion...

 - Barriers to entry, for example patents, restrict the number of competitors in a market. They may be deliberate, e.g. patents, or inherent in the good, e.g. water. Where they are inehrent, a 'natural monopoly' occurs. Monopolies may be a single firm in the market or created through collusion or cartels at the production or selling stage.

 - Advertising and product differentiation can help to enlarge perceived differences in products. This reduces the elasticity of demand for certain products and enables one firm to take control of a market, e.g. Apple.

 - Lack of consumer infromation can also allow monoply power to build up, as consumers are unaware of all of their options and therefore may be deceived into buying a certain product, allowing monoply power to build up.

What are the steps in answering a source based question?

The best way to tackle a source based question is to use CATPAD. In this: C: Content, i.e. what is actually in the source A: Author, i.e. whow wrote it, if they had any pre-exisiting beliefs you know about T: Tone, i.e. the inflection of words and ideas they are therefore trying to portray ...

The best way to tackle a source based question is to use CATPAD. In this:

C: Content, i.e. what is actually in the source

A: Author, i.e. whow wrote it, if they had any pre-exisiting beliefs you know about

T: Tone, i.e. the inflection of words and ideas they are therefore trying to portray

P: Purpose, i.e. why the author created the source in the first place, if they have any ulterior motives.

A: Audience, i.e. who the source was written for, can be linked to purpose closely

D: Date, i.e. when the source was written and if this has any historical importance, for example whether it was written before of after the Russian Revolutions of 1917.

If a source question asks you to compare the soruces it is impoartant you compare then on these levels and that you do not bunch the sources into types and only compare them in these bunches - try to compare as many as possible in as many different ways as possible.
