Welcome to Trevor Pythagoras

Trevor Pythagoras is a site all about maths where you can ask questions, buy textbooks and read lessons in the different topics within maths at a range of levels primarily aimed at ages 15/16 (GCSE) to 18/19 (A Level and Further Maths A level). The content of the site is based upon the maths syllabus I studied in the UK from ages 15 to 18 but each lesson is independent so if you are studying a different syllabus you should still find the majority of the material applicable and can use the request a post or questions features to fill in the gaps. Don't hesitate to use the interactive parts of the site (as a student I have plenty of time to respond to comments and answer questions)


Lessons

Using the links to the different sections across the top of the page you can find lessons on all the major topics. In each lesson there is a comments section allowing you to ask specific questions and expand upon the content. If you can't find a lesson on the topic you want you can request a post.

January 14th, 2011 No comments

It is often useful to be able to take logs of something raised to a power or to move a number multiplying a log inside the log. To do this the rule below can be used: logabc = c logab For example, log(9) = log(32) = 2 log(3) This can be used to either take [...]

Writing Vectors in component form

January 8th, 2011 No comments

Since vectors have sign and magnitude they can’t be written down as simply a a scalar (number). They can of course be given a symbol that we know represents a given vector, as we did in the introduction to vectors, but these can be difficult to work with. A common way is to use component [...]

An introduction to vectors

November 22nd, 2010 No comments

Vectors can be a strange concept when you first start using them in maths of physics but they are actually simple once you get used to them. Whereas we are used to dealing with scalars (otherwise known as numbers) which simply have a size vectors have both size and “direction”. That is vectors contain a [...]
