I am a first year collage student who have started his degree 12 years after A'levels. Due to this huge break in formal studies I had difficulties in understanding and recalling the stuffs that I did in my A' levels. However, with the help of this brilliant tutor I have build an excellent self confidence in Mathematics and studies has never been this easy...This is brilliant....May god bless all of you who works in this
To those of you who do Economics at degree level, I heavily reccommend ExamSolutions as he makes the maths a lot easier, espicially on topics such as this one, fractions, statistics, exponents, algebra and integration.
Does economic math get anymore complicated than A level math? The topics you listed are very simple at A lvl so far. And I’m considering an Econ degree
@@Enoo_ Can be, expect there to be lots of S1-2 content such as Standard Deviation, Normal Distribution but also extensions to that in Confidence Intervals and Binomial Distribution. Then with the normal maths content expect, a lot of stuff on Differentiation, Integration, Partial Derivatives, Algebraic Manipulation and Indicies.
Inside the brackets, you need 2 integers which multiply to give -3(the c value of ax^2+bx +c), but add to give 2 (the b value of ax^2+bx +c). These integers are +3 and -1. Watch this video for more examples ua-cam.com/video/IPbJll1M3y8/v-deo.html
It sounds like you do factorising by grouping. This method is by inspection. Look at this page.www.examsolutions.net/tutorials/factorising-quadratic-expressions/?level=A-Level&board=Edexcel&module=Pure-Maths-A-Level&topic=1172

I got an A in my mock exam... thanks alot my friend!
Excellent. I hope you can continue like that down to the exams. Best wishes.
ExamSolutions thanks alot my friend, I really do appreciate it
13 years later and it's still impactful
Good thing math doesn't change, unlike computer science where every old video is almost useless changes 😢
this is really useful thank. i'm doing further maths iGCSE and couldn't find something as clear as this anywhere else. thanks!!
10 years later, how’s life
yeah its been 11 years
Even after 9 years this is the most helpful video !!!
Turning points are stationary points.
Ooooooooohhhhhhh
Thanks a lot
You are my saviour. I learnt so much!
thank you! so helpful, learned a 7 mark question in 7 mins!
You're my saviour!
Couldnt find an efficuent explanation in the youtube channels i usually use.
Thank you
12 years ago. whassup?
@@Hana.J_57 😂. Still alive. I’m a big boy, working now. No maths in my life, but I still remember how to-the-point this instructor is.
I think your videos are the only reason I get good grades in maths. Great video!
Thank you and I hope they continue to give you good grades
Maths made easy! I love how you've actually made it easy and live by this motto throughout your videos! Thanks
Seeing videos good as this gives me hope for AS Maths next year ! Thank you Sir, keep the videos coming .
Thank you so much, sir! You are the BEST ever maths UA-cam channel and instructor!!
Watching in 2019 - SO helpful !!
love it.... its very clear and stright forward explanation....... thanks..... thats was very help full
I still can't believe how straight and nice your writing is. With a computer mouse too

@MEGIDIOT Your welcome and thanks
@Bimpstar Thanks
Thank you so much!!! I've watched three videos already and finally I get it!
Well done and thanks for your comment
Pls share what software and all the settings.. This is the best set up ever..

Always happy to read these kind of comments haha. Best of luck Paul
thanks, this helped me a lot
You're welcome
quite helpful 4rm Zimbabwe
omg this was so helpful!
Thank you sooo much. i finally get how to find cubic stationary points!
2x+6
thank you exam solutions ,this video was extremely helpful and well explained 😊
wow, thank you this video is extremely helpful
You are the best
Thank u for the clear explain
Glad it was helpful!
Thank you!
No problem, thanks for watching and possibly subscribing.
Great video it helped me out alot in many situations!! :).
i have a question and i have to find the values for x using dy/dx
so i would i find values for x if y=x^1/2 - 2x and y=x +9/x?
omg I loved the ad!
Thanks really good :]
13 years later... hows life?
very nice👏👏
Thank you sir
No problems, thanks for watching
@@ExamSolutions_Maths Sir can you help me figure out , why a gradient is never negative ?
@@shubfearless9928 Gradients can be negative. Have you watched the gradient playlist? ua-cam.com/play/PL5pdglZEO3NjBLZAuWqz_WXq-b6TtY20P.html
got my pure maths mock for my ucas grades on monday… time to cram revision! 😂💀
Hi. How is there a +3 and -1 inside the brackets (the fourth part) 2:52 Thank you.
I don't quite understand how to do it.
Inside the brackets, you need 2 integers which multiply to give -3(the c value of ax^2+bx +c), but add to give 2 (the b value of ax^2+bx +c). These integers are +3 and -1. Watch this video for more examples ua-cam.com/video/IPbJll1M3y8/v-deo.html
Thanking you!
saved me on my test tomorrow.
I wish you every success in it.
@jyim07 Cheers
thank you i learnt this like snap
good
Thank you
thankyou so much
+mily habte (saba) Pleased to be of some help.
im a bit confused are turning points the same as stationary points :S you dont have any videos on turning points :( please help!
ahh thanks got a bit confused!!
Thankyou
so how would u differentiate x squared + 6x?
2x+6
How did you do the factorization cuz usually we factorize in a way called the Middle Term but what was this??
It sounds like you do factorising by grouping. This method is by inspection. Look at this page.www.examsolutions.net/tutorials/factorising-quadratic-expressions/?level=A-Level&board=Edexcel&module=Pure-Maths-A-Level&topic=1172
What app do you use to edit these
how does differentiating 4 give us 0 . i mean 4 is basically having a power of 1 so 1*4^1-1 . hence 4^0 which equals 1 not 0?
4 is a constant and any constant differentiated is equal to 0 :)
bruh u cant differenttiate 4 cuz there is no x value with a power therefore abracadabra its gone
Basically constant are multiplied by x to the power 0 now when we differentiate x to the power 0 the answer comes 0...
YES!
thx
I never knew Gordon Ramsey did maths videos 😂
Thankyouuuuu ayyyyaaaaaa u saved my ass
Thx sir
Thanks for viewing
Like who is watching in 2023
What?? Still searching youtube for maths help. Are the videos from 2002-
Ive never heard more
how do you find stationary points if you cant differentiate directly
You should have went into more detail on the factorising part,never understood that part.
That is GCSE level factorisation, if you are doing this, you should know that by now.
y=-7 not -9??
JOSHUA IMADEIT huh
Thanks a lot sir.....read more
😊☺
You're welcome. Thanks for watching.
WHERE DOES X-1 COME FROM
i swear -4 to the power of 0 is -1
Nope, any value (apart from 0) raised to the power of 0 is 1.
YOU DONT SAY OR WRITE DETAILS AT ALL LIKE WTF IS DIFFERENTIATE
Great video it helped me out alot in many situations!! :).
