I saw this 'proof' many years ago. Can you spot the incorrect line?

I have begun a series of videos that are currently focused on the HSC Preliminary Mathematics and Extension 1 Mathematics courses. There is a free Ebook in PDF format that can be downloaded that contains 30 multiple choice questions which exactly follow the syllabus for Term 1. Inside the book there is a link which takes you to a page on my website (harderhscmaths.com) where there are 30 videos that give the solution to each of the questions that are in the Ebook. There are also (at present) Term 2 Preliminary Mathematics as well as Terms ! and 2 for Extension 1 Mathematics. They are available for $2.50 each. Regards, John Kinny-Lewis

You cannot learn mathematics by just going to class and watching the instructor lecture and work problems. In order to learn mathematics you must be actively involved in the learning process. Here is a link to past exam papers so you can study more effectively http://hsc.csu.edu.au/maths/mathematics/advice/159/advice.html
