@jshmtn What if that 4 years of data is about a child who has consistently underperformed relative to their true ability? One of the joys of one-to-one tutoring is being able to unlock a child’s true potential by finding a way to help them understand. Sometimes data can be misleading…

@pickover @edsouthall 8/rt5 in my head… (z angles, cyclic quadrilateral, cosine rule) …might have been neater with similar triangles instead of cosine rule but I couldn’t see it…

Hi @EmporiumMaths, could you please put to bed the LDS "trace" debate once and for all? The textbook (p13) clearly says that zero should be used for calculations. Various MS use 0.025 as a mid-interval value. If there is already clear guidance please could it be easier to find?!

@Cshearer41 8pi - since the two quadrants aren’t a specified size we can make them equal…

[Simon Ellis @simonellis42]

@Cshearer41 Nice. 3pi. (In my head after plenty of white wine so could be wrong…)

[Simon Ellis @simonellis42]

@boss_maths Thank you for these. Really got me thinking about about how to challenge pre-Trigs (is that a word?) to think spatially. Lots of variations possible!

@EmmaRaducanu Just fantastic - I’m setting my alarm for 2am so I can watch another fabulous performance. Win or lose, you have been wonderful to watch - a breath of fresh air and an inspiration to thousands of young girls like my 11yo daughter. #GoEmma

@Cshearer41 Nice one - I generalised and found that for an n-1, n, n+1 triangle the inscribed circle has Area=[(n-2)(n+2)/12]*pi which is nice... (especially as a 3,4,5 triangle has an inscribed circle with area pi - I had t spotted that before!)

[Simon Ellis @simonellis42]

@Cshearer41 16/25 - I love this! Always good when similar triangles and/or Pythagoras are the hardest things you need...

[Simon Ellis @simonellis42]

@diegorattaggi 3/8 by similar triangles...

[Simon Ellis @simonellis42]

@Laz_cam @360maths Not 3/14 but 30/119 which is frustratingly close to 1/4...

[Simon Ellis @simonellis42]

@360maths I was hoping it was going to be nicer (it looked like it should be 1/4 as both the big triangles are 1/2 - it was very close but the fraction has a denominator of 119) and, sadly, I can’t see an elegant way of doing it...

@RevRichardColes I am so sorry to hear of you partner’s death and am horrified to hear of the reaction of a few individuals. If they call themselves Christians they should be ashamed of themselves.

[Simon Ellis @simonellis42]

@Cshearer41 135 - I thought about the case in which the circles are equal in size...

[Simon Ellis @simonellis42]

@CoulsonDominic - play well today!
