@natcarrmaths @mrlouieevans I don't know. You'd hope so...

I just learned through a friend of his wife, that David Rayner (author of many maths textbooks including the classic Blue Rayner) passed away recently 😢. I worked with him for a couple of years and he was so funny, so clever and he helped many of us with his excellent books.

@MrWithersKS1 @GuyCarpenter567 This might explain what's going on. It relies on the second number being a string of 9s. Just adjust the number of zeros to match the number of 9s in the string 😊. Nice little puzzle!

@Whitehughes I often teach Gaussian elimination as a method to calculate Inverse of matrices to FM students...

@tm_maths @Whitehughes I bought a copy of MathType years ago and it still works. They keep trying to get me to upgrade to an annual subscription but I am fighting it! 😂

@robotmaths @SMART_Tech Not too long ago SMART put a watermark on EVERY page which only disappears when you are connected to a SMART board...who plans.their lessons whilst connected? We have to work with not being able to clearly see some of the screen. It's infuriating.

@robotmaths Has anyone got their free calculator? Someone posted a link on here a couple of weeks ago to get a free copy but mine has not arrived yet 😭

@langtoneagle @Ridermeister Followed by F, F, F, F, F ,F , F ,F ,F, F, F, F, F, F, F, F ,F ,F, F and then S! 😇

@rhalai28 @mrsouthernmaths @Whitehughes @BicenMaths @TLMaths @Lucyjc1612 The AMSP are currently running a programme of mock interviews. It is probably not too late to sign up for a mock interview with a volunteer Maths teacher 🙂

[Dangermouse @iisrootminusone]

@robotmaths @HawesMaths @MrSBarton94 @mathninja3 @MinsterMaths @MrBishop_Maths @reflectivemaths @Whitehughes Unfollowed too. Thanks for the heads up.

@mathhombre Sin(1/x) is another good example that a graph can cross a horizontal asymptote infinitely many times but long term tends to 0 😊

@Missy_E36 I had a parent complain about me for not being at Parents Evening - even though SLT told them that I was at the hospital for the birth of my first child...😢

[Dangermouse @iisrootminusone]

@LeightonM4ths @Whitehughes @robotmaths @TLMaths @tm_maths I think by this stage of the course they have met natural log (last chapter in Year 1 in the Edexcel books?). From this point on I (think I) only use Ln for equations (even if the base in the equations is not e - it's a habit of mine).

@robotmaths @zambukness You could always leave it to the 'Dr Frost North Star Fund' 😉

[Dangermouse @iisrootminusone]

@okimaths Not at all, I get that his resources are loved by many and that his sister really wants to keep his work alive and accessible. She is not on Twitter so I keep an eye out in case of website issues which the site do not make her aware of. 😊

[Dangermouse @iisrootminusone]

@LeightonM4ths @mathsjem @missradders The website host is upgrading something or other. Trifon's sister has sent an email to ask what's going on 😊

[Dangermouse @iisrootminusone]

@LeightonM4ths @mathsjem @missradders Have sent a message 🙂

@KerryDunton @Sheena2907 @missradders @robotmaths @DrBennison @Whitehughes I know a student who had not read through the additional information about the logic, only if, if and only if, etc stuff that mostly comes up in paper 2 document available on the tmua website ..😬 worth checking that your student has done that...
