With a name like that, you can almost envision a caped crusader swooping in to rescue you from the clutches of mathematical doom. 1st Class Maths, armed with unparalleled knowledge and expertise, becomes your beacon of hope in the dark abyss of inverse functions. As you grapple with the complexities of inverses, struggling to comprehend their elusive nature, 1st Class Maths appears as a guiding light. With patience and clarity, he navigates you through the treacherous terrain of mathematical inversion, unraveling its mysteries one step at a time. Through his teachings, the once formidable foe of inverse functions begins to lose its grip on your consciousness. No longer do you dread the mere mention of inverses; instead, you approach them with newfound confidence, armed with the tools bestowed upon you by 1st Class Maths. And so, thanks to the guidance of this mathematical maestro, you emerge victorious from the battleground of inverse functions, no longer haunted by nightmares of their complexities. In their place stands a sense of accomplishment and mastery, a testament to the transformative power of a skilled educator. Indeed, when faced with mathematical adversity, it is not uncommon to seek solace in the wisdom of those who possess the knowledge to illuminate the path forward. And in your journey through the realm of extension maths, 1st Class Maths stands as a beacon of enlightenment, leading you towards triumph over adversity.
Thank you so much! I've been having to teach myself gcse higher maths before mocks - we're doing a full paper, and I need an 8 to do further at sixth form! - as my class hasn't covered all the content yet. This channel has been invaluable.
Once again here i am binging your videos the day before my paper 3 gcse exam this time! You helped me understand inverse functions which I always struggled with, especially with all the simple steps ty. Also i have a question, for the 2nd example if my answer was 5x-1 instead of 5(x-1), would it still be correct?
Hey this is super helpful, also what is the difference of doing (the cube root of [(x squared - 58) divided by 2]) and ([the cube root of (x squared - 58)] divided by 2)? sorry when written its super confusing lol
The order in which you do the operations. In the first one you square x, subtract 58, divide by 2 then cube root whatever you get. In the second one you square x, subtract 58, then cube root then divide this by 2.
Hi. The working is as follows: f(x) = (3x - 4) / 2 y = (3x - 4) / 2 x = (3y - 4) / 2 2x = 3y - 4 2x + 4 = 3y (2x + 4)/3 = y f-1(x) = (2x + 4)/3 You cannot add 4 before multiplying by 2. You should multiply by 2 first.

BIG THANKS TO YOU for commenting this.
Samee I can't understand 😢
Man, you’re absolutely amazing, I thoroughly understood the topic just by watching once, I wish nothing but the best for you!!!
That's very kind. I am glad you understand it now :)

Man my igcse exams are near, and this video is so helpful right now. God bless you man, bring more content for us !
More to come!
Thank you so much! I've been having to teach myself gcse higher maths before mocks - we're doing a full paper, and I need an 8 to do further at sixth form! - as my class hasn't covered all the content yet. This channel has been invaluable.
Glad I could help! Good luck with the mocks.
Same!!!
Great video I showed my grandkids and he passed his gcses🎉
I have my maths olevels in a few hours. Thank you for this!!

Thanks and good luck.
Unfortunately no in response to your question. If you expand the bracket you get 5x - 5 so they are different.
@@1stClassMaths thanks for your help, so does this mean its better to not expand the bracket when it comes to these type of questions?
You can if you wish but I would leave it like that.
Thank you for this video. Helped a lot!
You're welcome!
Very very informative!!!!! Thanks!!!!!
You're welcome!
thank you so much man much love

Again great explanation of the topic .
Thank you!
Thank you so muchhhh, my GCSE pp2 is tomorrow and I didn’t understand this topic, it’s so much easier now you’ve explained it! 🫶
Thanks
Only few minutes into the video Nd I was able to reverse an inverse and also turn a function into an inverse❤😊
Why we are replacing x with y and y with x in step 2
ur a lifesaver
I wish I had this channel last year 🥲
Hahahahahaha
'Had' u mean 'knew' right?,same😊
Wish my teacher teach me like this 😭
You can send them the video 😅
Excellent
very helpful!
Glad you think so!
excellent video, thanks
Glad you liked it!
Thank u so much sir😊
Most welcome
thx this is very helpful :)
Sir something I dont understand.
f(x) = x/5 + 1
f-1(x) = 5(x-1)
Hi. The working is as follows:
f(x) = (3x - 4) / 2
y = (3x - 4) / 2
x = (3y - 4) / 2
2x = 3y - 4
2x + 4 = 3y
(2x + 4)/3 = y
f-1(x) = (2x + 4)/3
You cannot add 4 before multiplying by 2. You should multiply by 2 first.
@@1stClassMaths Im comfused
f(x) = x/5 + 1
f-1(x) = 5(x-1)
So helpful!
It's just clicked, I can now visualise It
Plz can you start a level and as level math
Might be a little bit of time but I will eventually!
@@1stClassMaths ok can't wait u saved my gcses
Yesss 🤗
❤🎉
bday ni wonyoung\^o^/
Plz be our school teacher 🙏
