Can u please explain the method of cylindrical shells to me….I’m an extension 2 teacher teaching it for the first time and I’ve tried looking on line but haven’t found that perfect answer. Do I calculate the volume of each shell as a cylindrical shell or do I use the rectangular prism. There is so much out there sometimes it’s hard to filter through all the information. If you could point me to a good source that would be great.

You’re in luck! I have actually just finished teaching through the volumes topic, and I’m in the process of editing the videos now – keep an idea on my volumes playlist and you’ll see the videos come up in the next few days.

Hi Eddie,

Your videos are great and a real help. T results are so cool 🙂 We don’t get taught them in the UK for some reason.

Please could you help me with identities which involve different size angles. For example:

Sin(2x) = Cot(x)

How would I approach something like this using the t results?

If you could make a video with a few worked examples that would be great.

Thanks
Umar

Yeah like how would you do something like

cos(2x)/(cosx + sinx) = cosx – sinx

cot(a+b) = cotacotb-1/cota+cotb

How could I do these using t results?

sin3x + sinx = 2sin2xcosx

How could I do this using t results?

Hi Eddie
I have a question regarding mechanics
I’ve looked at a few different textbooks now and when taking into account air resistance some textbooks will use kv (if proportional to v) and some will multiply by m and assume this force is mkv…I’ve watched a few videos from different people on line and they all use mass multiplied by the acceleration due to air resistance….which one I’d it

Terry lee uses kv so does Fitzpatrick while Cambridge uses mkv (am I over thinking this)

Thanks

This is a fantastic question and I addressed it just recently with my class. It’s a bit tricky to explain in text, so you can watch my take on things here:

Mr. WOO, can you please assist with expertise in Expert Systems and Neural networks and where to find documentation please? Your videos are GREAT!

I listened to your mathematical induction from other side of the globe . Your explanations are clear , thorough And very precise. I want to thank you for your excellent job
and great videos. Are you professional mathematician? thanks again.

Hi there Matt, thanks for writing! Glad to hear you find the videos so helpful. I’m not a professional mathematician – I’m a professional high school teacher. 🙂

Hi Eddie, I realised you don’t have a lot of complex numbers videos. If you end up doing them in class plss upload them. I’ve benefited sooo much from your videos and your explanations are actually taking my understanding from about 85% to 95-99% ish, (if that makes sense). Thx loads.

Hi Eddie, I really do like your YouTube video lessons! I am a maths teacher in Sydney and I would like to start YouTube video lessons for my students like you have done. Can you please tell me what kind of equipment do I need?

Hey Eddie,

Hope you’re having a great day!

I’m doing an expert roundup on my site and I think many new Math teachers using education technology products in their classroom like me would love to know your answer to this question :

If you could only use 3 Education technology tools/apps/sites for your teaching which 3 tools would you choose? e.g. WolframAlpha, KhanAcademy and Inside Mathematics.

As soon as I’m done compiling the results, I would inform and link back to your blog.

Thank you!
Ishan

Hi Ishan. The 3 tools I’d choose would have to be… Youtube (for obvious personal reasons), Desmos (nothing can beat it for graphing – it even does lines of best fit!) and Tweetdeck (for discovering/curating inspiring material and connecting with other educators). I know two of those aren’t education-specific, but they’re what I use to support learning (both mine and my students’)!

Great post. I was checking continuously this weblog and I amm impressed!
Extremely useful information particularly the closing phase
🙂 I take care of such info a lot. I was seeking this particular information for
a very lengthy time. Thanks and best of luck.

Hi Eddie,

Your enthusiasm for maths is contagious.
It will infect any curious mind with wonder.
You’r benefiting ..kids all over the world.
Also you’r a ‘teacher of teachers’ – The Teacher
A place is already reserved for you in the great hall of mathematics.

Keep it up.

Eddie. I just caught you on the ABC and I am delighted to know you are in the system making a difference. I am an old man now and have been watching our education standards slip dramatically from when I was a student. It has nothing to do with money. It has to do with direction and we have lost it in the last forty years.
Your excitement and enthusiasm in infectious and I hope you can infect the nation. Good on you mate.

Hi Eddie
What a terrific explanation of databases and using sql, when I was at uni 50 years ago no one ever actually explained anything…… your students are very privileged to have your expertise and gifts to give them a great start in life.

I think you are an inspiration Eddie Woo. I’m a grandparent and one day I’m going to show my grand babies your videos. Your mother would be so proud of what you have achieved.

Hi Eddie, on behalf of most if not all Australians i would like to thank you and your family for the light and hope you bring to students and parents. You are the best example of how important respect and kindness in all our lives is. I am so pleased that through TV i got to know you.
Love you mate.

Hi Eddie, I’ve just came across an aritcle about your Maths videos and have actually watched some of them. You’re brilliant and you made understanding Maths so simple and logical. Thanks so much for sharing your knowledge and insights on Maths. I hope to be able to influence and get my kids “sucked in (as one of your students commented)” into Maths too. Please continue sharing your knowledge and influencing kids not just in Australia but around the world too. By the way, I’m a mother to two school going kids in the United Kingdom and I just love the way you explain fractions. BRILLIANT! Thanks again so much!

Thank u from a mum trying to teach her son high school maths that’s is so different from when I went to school, and in a small country town there are few teachers willing to tutor.🤓

Hi Eddie, Just watched a recording of Australian Story. We need more teachers with your passion and understanding of children in our profession! May you keep inspiring both students and teachers!
