I find formulas obfuscate the idea. As others have said it's always the angle between the initial and final velocity vectors. I give classes this to help them realise why formulas aren't great

I’m kinda curious what happens as this number gets bigger. Will it start using standard form? A couple more emails today will get me to 5 digits

Happy Halloween, shoppers! 😱

I don't know about formal definitions, but Rudin lays it out explicitly!

After watching Snow White last night, I’m now welcoming woodland critters into my lessons 🐿️

Does this get you started with the first one?

A bit more detail on my shake-up of Y12 Maths. We're going to begin with coordinates and lines. Surds will arise naturally from Pythagoras. Rationalising denoms (not quite so naturally) from gradients between two points. First taste of modelling and stats, too. Even vectors get a look-in

Just been reading about George E P Box - interesting back story from the Army in WWII to a career in statistics. Notable quotes: "All models are wrong, but some are useful" and "Statisticians, like artists, have the bad habit of falling in love with their models." 😄

I'm new in town, so hopefully can rebuild my A level Maths network here. I might do a series of posts about my plans for reorganising our Y12 scheme of work... Step 1: post-its! I'd love to hear if anyone has made interesting choices in their sequencing of topics
