@Ridermeister@marksandspencer It's hard not to read it as, in contrast to all that maths you don't like, here's some you will.
But, it's also hard not to read the implied dislike of maths as we (maths teachers) are so used to seeing that from the media. Perhaps it's not really there in this case? Boo if it is
@mrallanmaths "Of course you can go, but you owe me 5 minutes at the end of the lesson." Or 10 minutes if you take longer than 5 minutes (always round up 🤣)
@overleaf Thank you for sharing. It doesn't impact the article, which is very useful, but you may wish to double-check the sin addition formula at the top.
@jamestanton It is possible, in both cases, to create N triangles with a shared vertex within the polygon.
On a plane, the interior angles sum to 180N - 360 (the sum of the angles around the shared vertex).
On the cube, the interior angles sum to 180N - 270 (the 3 right-angles).
@Sheena2907@Advanced_Maths I love these because pupils are always convinced they've got there after finding 4 solutions. I've had a lot of practice of my evil chuckle on this task. 😁
@TLanokia@oldandrewuk I once had this and replied asking, politely, for the reason for the meeting. No response. I eventually rang her PA who didn't know but said she would ask.
It turned out to be about someone else. Afterwards, I said it wasn't right to be summoned without a reason. She giggled...
@StuartLock@EmathsUK Are you waiting to get it back still?
I truly horrified my eldest by pretending to eat it, hack it up, and then replace it on her face. Her expression will stay with me forever 😂😂😂
@paddymac_maths@MathsTechnology Exactly this. I always talk about replacing x when discussing transformations. I like throwing the second version as a "how else could we have done it?" problem, pointing out potential pitfalls along the way.
@catrionateaches @mathforge Do you introduce permutations first? Choose 5 seats from 20 in the cinema for you and your 4 friends... to get the n!/(n-r)! notation embedded?
