Thanks that is very kind! I am working on it but it takes me about 10 hours per video. I do a lot of research and analysis of past papers to write the questions and the animating, recording and editing takes a while too. Hopefully one day I will have everything covered.
@@1stClassMaths Wow thats a lot, I really appreciate the time and effort you put into these videos. I dont know where I would be without your channel. Thanks so much.
Thank you . I have always had a problem identifying a right angle that goes through the shape . Your clear explanation made it easy for me to follow . Thank you sir 🙏.
I like that you mentioned to wait until the end to round. I've seen a number of other math channels not adhere to that idea. It always bugs me, as I always try to keep amounts as exact as possible until the end (inverse trig functions are particularly annoying in these cases, as there often are no "exact" amounts other than the trig expression itself), so my solutions come out slightly different. This can make it more difficult to verify I got the right answer, especially if I came about it via a different method than the instructor...
it's always the wordings that catches me off, I know how to calculate the angle EGH (for example), but if the question were to ask me to calculate the angle between EF and the base ABCD, I wouldn't know what to do. Could you make a video on that please? 👍Thanks!
I think you can help me. This is the challenge. Given a 20 foot container needs to be lifted from the bottom corners and the angle at the top must be at 90 angle between diagonal chains (where the chain bends inwards) to the middle center of the container. What is the length of the chains, or just one chain, since it will be symmetrical? Container dimensions. L 6.06m H 2.59m W 2.44m
Can we use formula d^2 = a^2 + b^2 + c^2 for 3D pythagoras? Does the mark scheme allow it for edxcel GCSE? Do we still get full marks for correct answer?
When working out length of AG my math teacher taught me a cheat. Just do root 9^2+8^2+20^2 and u will get 23.3. Works for any diagnol length. However would u get all the marks in an exam like working out marks?
It is because the whole of the plane ABCD is at a right angle to the line AE. Imagine ABCD is the floor of your room. AE is simply a vertical line so will make a right angle no matter which corner you join it to.
if you were given the base length in example 6, lets say for example it was 10cm. could you draw a line from M to the midpoint of CD and use pythagoras to find your perpendicular height using 15 as the slant height and 5 as your base height since M to the midpoint of CD would be half your base height which would be 5?
I am afraid that would not work. The length from E to your new point at the middle of CD would not be 15. Look at the triangle EDC and you can see that your line goes right down the middle splitting it into two right-angled triangles. This means the hypotenuse is 15 but your line would be the height and not the same length. Hope that makes some sense! Basically it isn't 15 all the way around the pyramid.
Afraid not. I do not round the number at all. Writing … implies I know there are more digits that are not written. If you continue watching the video I explain premature rounding and the need to use the exact value.
Possibly. Sometimes exam boards give a random of answers to it might need to be between 2 set values. The best, most accurate and safest thing you can do though is not round until the end.
for some reason when i typed 4.6... squared on my calculator the answer was 21.48558814 and i was confused, i typed it again just in case i messed up with the numbers but came up with the same answer again. Which one is right?
You’re my favourite maths teacher by far! It’s just a shame your videos don’t cover the whole syllabus

@@1stClassMaths god bless you
@@1stClassMaths great guy
nailed it, I can bet you once he has completed the syllabus he will be beyond Maths Genie
Another life saver by 1st Class Maths!
I think we all can't thank you enough.
Genuinely one of the best educational channels I have seen on this platform. You must be a wonderful teacher.
What a really nice comment! Thank you!
Visualising maths in TH-cam makes it easy. Thanks alot
PLSSSSS never stop these videos
it really very helpful!!!!!! NEVER STOP POSTING PLS PLS!! you have no idea about how all these videos helps us!!!
flipping brilliant mate, touch me everything i needed to know the night before. have a great one xx
Thank you . I have always had a problem identifying a right angle that goes through the shape .
Your clear explanation made it easy for me to follow . Thank you sir 🙏.
my mock exam is literally tomorrow and whatever i know about this, i learnt from you. thankyou so muchhh!!!!!
Best of luck.
Your videos have helped me out alot and I've understood ...I'll say you are the best mathematics teacher
Thank you! Perhaps you're the best student!
Thank you sir 👍
Welcome!
thank you very much may god bless your whole live for saving me from falling my math
i have a test on monday and the only thing i dont get is trig 3d so u helped me a lot thanks

Yes that is premature rounding and they shouldn't be doing that!
I'm watching this just to help me understand these math concepts for next year

I would say drawing out/shading the bases and lines your talking about would help you visualise it. Just connect the letters they say. You got this
Truly a life saver
So underrated ❤
I LOVE THIS GUY HE HELPS ME SO MUCH
THANKS FOR COMMENTING YOU HELPING ME SO MUCH ALSO.
May you please do angle of deppression and angle of elevation❤
hi sir, can you pls make a video of 2 of the hardest types of qns for each topic in 0580?
I think you can help me.
This is the challenge.
Given a 20 foot container needs to be lifted from the bottom corners and the angle at the top must be at 90 angle between diagonal chains (where the chain bends inwards) to the middle center of the container.

Container dimensions. L 6.06m H 2.59m W 2.44m
what’s f in 20f, I can help
2.86m
Thanks very helpful
Sir it really helped me. Thanks alot. Brilliant teaching
Happy to help
can you do trigonometry 3d based on igcse olevels
Wanderful ❤
Thankyou so much this saved me the night before my test 😅
You're welcome 😊Hope the test went ok.
My school needs to hire this guy
They can if they wanted! Page on my website. :)
Please do the unit managing money
Thankyou so much ❤❤❤
Your videos help me teach
Great video!!!
Can we use formula d^2 = a^2 + b^2 + c^2 for 3D pythagoras? Does the mark scheme allow it for edxcel GCSE? Do we still get full marks for correct answer?
Yes
Thank you for such a quick reply.
I've just found your channel and love it.
can please do projectile motion,
what topics haven't you covered for edexcel?
can u go through conditional probability?thank you
Working on this one.
What if in example 3, we were instead asked to find the length of the angle GC, how do you do that? please reply quick
How would we know which triangles we draw on are right angled or not
please do volumes of cubes
Can you pls make vedios explaining grade 11 maths topics
I ❤️ 3D trig and Pythagorean theorem 😍
me too
Very helpful
Glad you think so!

Yes you can do this.
how do we get the numbers we ha dbefore
can you do area and capacity problem solving please
Thank you so much . These videos are a life saver
Glad you like them!
Please do circle theorems
My most viewed video is on circle theorems. th-cam.com/video/dBIlCD_JF9Q/w-d-xo.html
Will you help me.. how angle EAC= 90, as far my knowledge EAD is 90
It is because the whole of the plane ABCD is at a right angle to the line AE.
Imagine ABCD is the floor of your room. AE is simply a vertical line so will make a right angle no matter which corner you join it to.
Hi there, instead of using EA 4.78 ... can we just use 14sin(20)/root 296 ?
Yes because 14sin(20) = 4.78...
if you were given the base length in example 6, lets say for example it was 10cm. could you draw a line from M to the midpoint of CD and use pythagoras to find your perpendicular height using 15 as the slant height and 5 as your base height since M to the midpoint of CD would be half your base height which would be 5?

This means the hypotenuse is 15 but your line would be the height and not the same length. Hope that makes some sense!
Basically it isn't 15 all the way around the pyramid.
@@1stClassMaths thank you for explaining makes sense now i thought it was 15 all the way around the pyramid
you made a mistake on 10:16 as you rounded it off to 4.78... but its 4.79
Afraid not. I do not round the number at all. Writing … implies I know there are more digits that are not written. If you continue watching the video I explain premature rounding and the need to use the exact value.
thanks this is now ticked off the topic list
Thankyou stay blessed
How are we supposed to know which triangles you draw on are right angled or not?
Like going through the shape it's not clear which if any angles are right angled
sir can u do harder venn diagram questions?
I will get there eventually :)
@@1stClassMaths tysm 😊
very clear thank you
Welcome 😊
Love it
Thank you sir
hi sir, would we get the formula for the volume of the pyramid for 2024 gcse's
No I think you need to learn this one.
Do you do phisica
Afraid not.
Please make predication paper 2
Pls do calculus🥺
If you didn’t use the full value of EA on Q5 for the last part would you loose the mark
Possibly. Sometimes exam boards give a random of answers to it might need to be between 2 set values. The best, most accurate and safest thing you can do though is not round until the end.
This is like cognito alternative
ye lol
Cognito improvement*
5:42 and i got paper 2 at 9. im so cooked
Tall as for the angle theorem 😮😮😮
Yes
Yes
I love u please dont die
Working on it.
