TobiI've come across https://risps.co.uk/ and their equivalent for #FurtherMaths #ALevel which are honestly beyond excellent. However I would love to know if there is something similar for #GCSEMaths
TeacherBowTieThe textbook I use with my Further Mathematicians says this about Euler's Formula:
'It is a definition, so it makes no sense to ask why it is true or how to prove it.'
I vigorously disagree.
What are your thoughts #MathsTooter?
Colin the Mathmo@TeacherBowTie It's worth using more #HashTags so people can do a "semantic search":
#Teacher #FurtherMaths #Puzzles #Geometry #GeometricPuzzles and so on.
People don't use them much, so searches don't turn up much yet, but as time goes by I hope they will, and they will.
Meanwhile ... see if you can find all the integer solutions to:
\( ð!+8=2^k \)
And welcome!
