the 8 dislikes are from teachers who are mad that they still couldnt get us to understand this after 5 lessons and you did it in 12 minutes
Haha that makes me feel a lot better about the dislikes! 😂
@@TheGCSEMathsTutor legend
This guy will be the reason I pass my maths GCSE, everything he says makes sooo much sense thank you!
Amazing news! So glad to hear it’s useful 😁🙏🏼
When the exam starts
no one:
me: *ayatul-kursi* Bismillah hir rahman ir raheem lol :)
Good luck
@@barbarians7866 youre not the only one, it gives you more luck lol
@@xpresslotodo460 Alhamdullilah! May Allah make everything easy for you! I wish you all the best :)
I dont understand how your make everything so much easier to comprehend
I’m top set maths at my school and you’re the only one who actually explained this to me in a way I can understand. It took many hours of revision until I found you but it was worth it!
You have been sent by god 🙏🙏🙏 tysm
Well thank you!!! 😁 my pleasure glad you are finding use in the channel!
I got a 98% this term and you where a HUGE contribution to that...fan of your work ...it's honestly amazing how so many people (including myself) can benefit from this treasure ...it's an immense thank you from me
Congrats on getting 98%
That's amazing!
super late, but that's awesome, congrats!
Omg thank you so much, every time I do a past paper I just skipped function questions out because they looked so hard, you make it so easy, definitely won't be skipping those questions out again :)

@@djwafflez5133 lmao this was two years ago and i have a level maths paper 2 next week
@@seanobi4189 Got my GCSE maths today revising this while on the toilet 😅

@@fatima-de2yv fully sent it with this being my only revision , got out with a 7 and doing a level maths now 🙏🏌️
I take igcse in new Zealand and my teacher explains things very vaguely so this in depth explanation was amazing
So glad to hear that the content is working for you! Well done for being proactive and putting the time in to deepen your understanding 😁🙏🏼
Excellent knowledge and explanation again...But I have to say- What an INTRO...LOVE THE MUSIC!!!
Aaryan Ramani Haha thank you! That intro took me ages to make 😂🙏🏼🙏🏼
@@TheGCSEMathsTutor you made it?? i love it, it always lightens up the mood when coming to study math
You are an absolute legend. Without a shadow of a doubt you should be nominated for an award for the magnitude of students that you have aided in their path of gcse Maths🎉
I might be the only person watching this video to help me with my University studies lol...
Can be demotivating to see all this stuff taught at GCSE and yet here I am at the end of year 1 Computer Science at Uni learning it for the first time so I dont struggle next year lol but we vibe
edit: I must also thank you so much, these videos are so easy to understand.
hru doing now

how will this coronavirus pademic affect students currenly in yr 10 moving into year 11. Will we be behind and if so will they make 2021 gcses more easier
i dont encourage them to relax although everyone knows that it is annoying to read during this pandemic.However, they might use the fact that we/they have social media platforms and ways to get in touch with tutors for any help and make them harder.
Meerkat King As it stand we need to wait for Ofqual to make a decision, as soon as there is more information I will let you know 😁🙏🏼
No joke I spend an hour on text book and useless videos. This video actually made sense 😅 tysm
Thanks man seriously.
Better than any maths lesson I have
Thanks, useful video.
Omgggg this is AMAZING THANK YOU-✨✨
My pleasure! Glad to hear it’s helpful 😁🙏🏼
The intro's a vibe.

YOU ARE GOING TO SAVE ME AT MY IGCSE PAPER TOMORROW, THANK YOU AND PLEASE CARRY ON THE GREAT WORK, YOU ARE A G 🫡
Hey man, which app do you use for all your videos? I really like how the pen options are at the top

very well explained
Saved me yet again
Thank you so much
What a video thanks a lot 👍
just thank you!
Thank you so much!
Thank you so much ❤️
so helpful
Your voice is so soothing.
woah mate
What the hell are you insinuating take your mind out of the gutter and elevate your thoughts beyond the vulgar.
This is the only part of maths I didn’t understand. In my recent mock I got 67/80 (84%) however without functions I got 67/73 (92%). You’ve made it so much easier!
You are so clever how much do you reckon you revise a day and how long have you revised for Ik it is different for all people but I’m just curious
@@user-yf6ns7ji4f I didn’t revise at all as maths has always been my strongest subject. However for stuff like sciences I revised two hours per subject per week, from the CGP revision guides. The longer before the exams the better, minimum 7 weeks for top grades, unless you’re willing to work your ass off shortly before the exams.
@@matthudson9705 you are truly blessed what are your grades looking like for science
@@user-yf6ns7ji4f Biology - 9, Chemistry - 8, Physics - 7
@@matthudson9705 That's literally what everyone says. Bet u revised at least 3 hours a day.
Amazing video finally understand
Great news! Thank you 😁🙏🏼
thank you boss ❤
I now get composite functions thank you so much
I’m so glad to hear that! Well done 😁🙏🏼
you
are
the
FRICKING BEST HOW DID YOU MAKE IT SO EASY BRO I THOUGHT I WAS GONNA FAIL MATH FOR SURE
So glad to hear that thank you! 😁🙏🏼
thanks, these are great!
fizzabatool Great to hear! 😁🙏🏼
Thank you
on the first couple of questions do you just leave your answer as the numbers or do you have to do something else with it
THANKYOU I LOVE YOU
thank you so much
I struggled so much in school with this confusing method they made us learn but after watching this I quickly understood functions and can finish questions faster than my peers xd
Amazing news! I’m so glad to hear the channel has helped 😁🙏🏼
Thanks keep it up mate!
Glad it helped! I will do 😁🙏🏼
I had the first question on my maths mock yesterday, and I had no clue how to do it; I have never learnt that ever!
how did u do
Thank you❤
You're welcome 😊
very helpful!! thanks
k sam Great to hear! 😁
@@TheGCSEMathsTutor will you be doing any more exam walkthrough videos?
k sam I shall be 😁👍🏼
8:31 Would you simplify to get 2x + 3?
thank youu 🥺
No problem at all!!
nice video! quick question, if u work out what fg(X) is first lets say and then work out what fg(4) is that fine?
Absolutely! A more advanced process but a very logical one 😁🙏🏼
@@TheGCSEMathsTutor means a lot god bless u or have a great day
how will this coronavirus pademic affect students currenly in yr 10 moving into year 11. Will we be behind and if so will they make 2021 gcses more easier ..............Also any advice for yr 10s
this is good stuff
Can you make a vid about functions like: g(x) = 12 - x4 when x is or is bigger than -4. What is the biggest value of x that satisfies the equation?
Marcelino Castrillo Molina This is really just an inequality, so 12-x^4>-4 which rearranges to 16>x^4 and then 2>x or x
I still don’t understand why teachers can’t explain the way this guy does ,,
I understood all of the vid Untill 11:20
The explanations was so good tho
What threw you off at this point? Glad you enjoyed it 😁🙏🏼
@@TheGCSEMathsTutor I think I understand it now so thank you
real gcse exam tomorrow, i sincerely hope this helps me 😭😭
only 5 minutes in and it already makes so much more sense oh my god thank you so much 🙏🙏
good luck !!! you'll do great 🙌
@@erenyeager6668 thank you mr yeager your support is greatly appreciated🔥
Good luck I’m learning this rn 💀💀
@@unclecondog9807 we got 1 hour left lmao
at 7:40 are you required to factorise ?
hi sir, do you have any videos on polynomial functions by any chance?
czcams.com/video/a5x4lwnvHM0/video.htmlsi=djtPXxZNTURxNl8G
thanks
ATORAT Gaming my pleasure 😁🙏🏼
i never understood this tysm
Quick Question: Why do you switch around the x and y @ 11:32 ??
All explained here: czcams.com/video/EdQYcAsu7wA/video.html 😁🙏🏼🙏🏼
Wowwwwwww intro is so cool
Thank you 😊
What's the rule you can just switch the x and y at 11:35
Umm. Hi I had a question inverse of composite function isn’t in GCSE 2025 syllabus right?
Instead of finding what f= when 4 is there
Can you just put f into g then find out what it is if 4 is there or is your way the right one?
👍😁
Sorry to say your better than Corbett maths
