Just started 2nd order ODEs, decided to start with coupled 1st order.
Rationale:
1. Modelling. Start with y'=ky modelling a single population, bring in a second with interaction.
2. Exponential. Solution to single pop is exp, so reasonable to try for double.

In #MathsToday I taught the Chain Rule, one of my lessons was moved to a different classroom on the other side of the college due to resit exams and I can't tell you how traumatic it was. The tables were smaller and the interactive board didn't work. First world problems I know... #ALevelMaths

In #MathsToday I did some CPD for my department on using the CG100 calculator for #ALevelMaths. I used some of the excellent video tutorials by @tayyubmajeed.bsky.social - very helpful, thank you!

A Year 11 student wrote this question as an extension in #MathsToday following on from the questions we worked through below 😮
Definitely will be a fun qu to give my #AlevelMaths classes next week!

Been teaching Quadratic Inequalities and Trig Graphs to my year 11s recently so put this together for them as a challenge!
Will also give it to my year 12s and see how they do...

Nice little activity with further today, give them a function, eg f(x)=x²+1, {x:x<3}, and they have to say whether it is many to one or one to one, and if it is many to one a reason why (eg in this case f(-2)=f(2)), & if it is one to one to give the inverse function #alevelmaths #mathstoday

#ALevelMaths teachers who use the Casio calculators (CG100 or fx-991), what things do you teach students to always use the calculators for? Thinking along the lines of the "solve" function for equations, or using the linear simultaneous equation solver if a pair comes up in the middle of a question.

Enjoyed Q25 from the SMC and in particular liked that my own solution isnt one that is demonstrated in their videos

In #MathsToday my #ALevelMaths students did some work on trig identities using the double angle formulas. I'm excited to get stuck into differentiation after half term!

Really nice to be able to share Senior Maths Challenge results with students today; lots were pleased with their awards. 14 qualified for the Senior Kangaroo (including some Y1s), and a lovely student who still doesn't realise or believe quite how good she is qualified for the BMO1 🥰🥇🥈🥉 #ALevelMaths

Y13 did their first set of integration looky-likeys in #MathsToday. Looking forward to lots more of this in the next few weeks!
The last one was a bit mean (I put it there to slow down the fast finishers) but they did manage it when I gave them the right substitution. #ALevelMaths

In #MathsToday my year 2 further maths students were introduced to the exponential form of a complex number. I always love sharing Euler's identity with them... three of the big-player constants of maths combining together to make -1 always feels like an important moment! #ALevelMaths
