Hi everyone,

I need the book of which these problems is derived from.

Any help?
​

 

Textbook? are you sure?
Two of your three images are hand written.

Some ones's old lecture notes plus a typed problems sheet?

 

I'm sure that these problems are from textbook. Don't mind the hand written figures.

 

Well the questions refer to fig1, fig 2 fig 3 etc.

And the figures are definitely hand written.

Further you haven't shown the whole page.
What else does it say on the page that we don't see?
Textbooks would surely have at least page numbers.

I have quite a few old textbooks so I could quite quickly check say page 137 in each one for your text.

And why can't you post the pics here?
More folks might take an interest then.

 

That's a pretty poorly written book, it's fraught with errors.

I'd bet it's a book written outside an English, as a primary language, country, if it's a book at all.
