Hi Mr Wee,
A print version of the website would be feasible. It will be
better if you enhance its usefulness with the inclusion of
essential notes for each topic.
To take the topic of function, inverse function and composite
function as an example. Besides the formula, it will be more useful
if essential notes are provided as a recap for each topic ie
1. to state the use of the vertical line rule for any
function and the use of horizontal line rule for one-to-one
function (ie the existence of an inverse function) and the use of
dy/dx to prove an increasing or decreasing function and hence the
existence of a one-to-one function.
2. to state the steps to find an inverse function
(including the use of completing the squares method) and
composite function and to state the relationship among the domain
and range of these functions.
3. to state the conditions for the existence of inverse
functions and composite functions.
4. to state the domain restriction to obtain an inverse
function and composite function.
5. to state the use of the line y = x to find the
relationship between a function and an inverse function.
I believe Mr Chui will be glad to help you to publish the
formula booklet and he can also help you to sell it to the JC and
MI students and in Popular Bookshop, Big Bookshop and other
bookshops.
May I wish you every success in this project.
Thank you for your kind attention.
