Our answerers were gino3141, CPhill, roasala, school, tyvlad012 and Alan. Thanks all.

Interest posts:

1) Here is one for middle level trig students to have a go at - I have not actually finished it.

2) Simplifying indices - they can be messy

3) Area ratio of inscribed to circumscribed circles - Thanks Alan

4) Unusual area question

5) Another great length question. - Great pre-runner to calculus :)

6) I like this difference of 2 squares question because I like how rosala always tells us when she does not understand our explanations. Thanks rosala
