Pls, Sir. i have tried solving test questions 4 and 6(chapter 7) all to no avail. they weren’t included in the notes. i would like you to explain in details. MANY THANKS.
I don’t understand what you mean when you say that they weren’t included in the notes.
Firstly, there are answer in the notes to all of the examples and tests – if you look at the contents page you will find them.
Secondly, the methods involved are covered in the notes!
However, if you are using the notes on their own then it is ridiculous! It is made clear in the notes that they are lecture notes to be used with the free lectures. In the lectures I go through the examples in the notes and explain.
