This video covers indices, surds, quadratics, inequalities, sketching graphs, lines and circles, factor theorem and binomial expansion in under 25 minutes. The remainder of the course is covered in AS Pure Maths II in 30 minutes.
*Timestamps:*
0:21 - Indices

You are an absolute godsend and i respect you for taking the time to write this. Thank you very much
God bless you
THANK U SO MUCH 😭💕
I'm retaking the exam, and this is super helpful. Thank you so much!
Im going through this on the morning of my mock and Im probably going to fail but thank you anyway
@@stresslimit I actually ended up with a C which I'm pretty happy with
@@charlieamorris04 i would like your knowledge
Omg same
It was very rewarding to do the problems
I was very paranoid about my exams this helped me to get some confidence in myself you made it look a lot easier and simpler thanks for your effort keep it up 👍👍.
Amazing video to refresh the memory after summer holidays!
this was extremely useful for my revision and I am very thankful.
thank you for your efforts, this was helpful indeed
saved me last minute thank you :)
Yaseen Khan asked
Why do we do x=0.1 at 21:27
We have to estimate 1.025^8 so we want the 1 + x/4 = 1.025, which we can solve to find we need to put x = 0.1
Please help
@@ahmedraza4410 factor out 0.25 from (1+ x/4) then solve, u get 0.1
Thanks this was very helpful
Super helpful hope you make more videos in the future :)
Hey man great video, I loved how easy you made all the explinations.
Edit: at 15:39 would the answers not be -3+sqrt3 and -3-sqrt3 as it asked for the y co-ordinates, or is your presentation acceptable for an exam board.
Thank you
I appreciate this video, also you 100% sound like Sir David Attenborough
Everywhere i go.... i see your face.
poggers
thank you very much sir
Thank you!
for coordinate geometry, where did you get -2.5 from?
L1 has the equation y = 4x/5 + 2. S is the point where L1 crosses the x-axis, therefore y = 0. Substitute y = 0 for y = 4x/5 + 2. 4x/5 = -2. 4x = -10. x = -10/4 = -2.5
@@saebre. thank you so much
thank you sir!
Damn thanks man papaya gods sends regards ur one lucky guy
Hello there, at 10:35 how did you get 6 as the y coordinate for P? to find the Y coordinate for P, I made x=5 and its was y=5+2 which was 7 instead of 6. I'm not sure if I misunderstood the question or not.
Y = 4/5 x + 2, when x=5, 4/5 of 5 is 4, plus 2 is 6
Waiting this to prove to Miss T I did revision
acc nvm lol you made 2nd video for calculus : AS pure maths 2 in 30 minutes for people who need that video
Thankyou sir
5:00 for the second simultaneous equations question I found k to be a half, skewing the answer to c also. I cannot understand it to be 1/16?
64k^2 - 4k=0. So when u take 4k out u get 4k(16k-1)=0 hence giving 1/16
@@mehh_01 thx man
@@Gk1_18 no prob
b^2- 4ac, therefore u sqaure both 8 and the k giving u 64k^2, u only squared the k so u ended up getting 8k=4 and then getting k= 1/2
Thankyou dear sir you are Great sir
Thank you so much sir
got my AS level m/j boards in almost a week
The last resort
hey @ 3:35 im confused as to how you got 2x^2 + 9x +4 = 0 as the thing. I collected the like terms
they divided the whole equation by 4

hey the pure mathematics 1 book has AS and A levels combined in 9 chapters , until where does the AS level part stop like at what chapter?
Sorry I'm not sure that I know the book that you are referring to.
haii if you're talking about the IAL Pearson Edexcel one, the P1 (pure mathematics 1) book as well as P2 (pure mathematics 2) are considered AS, and then P3 and P4 for A2/A-levels. They are 4 different books.. 2 for each level with a combination of mechanics (M1) or statistics (S1) but that depends on your school or educational system
so ask your teacher to make sure about this
0:45 how do you turn numbers into products of prime numbers?
Most common method is factor tree. Check out any Gcse site
11:42
so if the equation for the line 'L2' is y = - 5/4 x + 49, then should'nt the equation in ax + by + c = 0 form be 5x + 4y - 196 = 0?
L2 is 4y = 5x + 49
Sorry 4y = -5x +49
At 12:02 Why wasn't the base 7.3(you add 9.8 and -2.5) instead of 12.3
We are adding lengths. SO is 2.5 and OT is 9.8, so ST is 2.5 + 9.8
Which year is that in 10:00
for the first simultaneous equation question why is y equal to 3 and not -1/2 but for -4 its the same?
You substitute x=-1/4 in the first equation y=1-2x = 1 + 1/2 = 3/2
@@tonydebling thank you!
Hey,
a quick question
do this video (and the second one to this) cover all the topics in AS level Maths CIE - Cambridge Assessment International Education ???
If not - then can you tell me how much percent of the topics have been covered according to AS Level Maths CIE....
I am talking about only the book of PURE MATHS 1
Sorry I've not looked at this
hi, i have the same question. did u pass your pure math 1 exam with this video?xD or did you use any other resourses ?
Time to revise for my AS paper tomorrow hehe
going through the vids, exam in 2 hours kek
hey can i use this for international edexcel?
Yep, should be fine.
i hate math
Me too, Btw how are you ?
@@yutirwsna7715 at this moment, I am doing alright, what about you?
I’m ok btw
@@subza9592 That's good, have a nice day
@@PazzazItsMe how’s math going for you
at 12.51 dont you divide root 34 by 2 because you find d which is root 34 but you want r ?
No, PQ is the radius not the diameter.
Thankyou so much. U saved my life 🥹
11:04 how did you get (y-6) and (x-5)
You are told point of intersection of lines has x coord of 5, so subst this into the equation of the line given to find y = 6 so point of intersection is (5, 6). So equation of perpendicular line is (y - 6)=m(x - 5)
do you have anything for AS Further Maths?
Sorry, not at the moment
@@tonydebling all good👍
@Tony Debling will this help me achieve an D so far I've been getting U's on my exams and I want to get higher I got A in computer science and A in business maths I understand but I struggle to know what methods to use especially with how questions are worded and I have to get a D to enter second year and my exams are from 23rd I did answer booklets but I get stuck on question which I should know maybe could yu help I so badly need to pass I want to do maths
i am literally the exact same here, exam is on the 18th this month for pure AS and I'm failing exams but passing business and computer science. @Tony Debling anything that will help me get to second year would be amazing and I'm on WJEC exam board
@HQS computer science is like year 8 stuff in first year trust me there’s barely any correlation between maths and cs
At 3:06 how do you figure out x. Is it just through logic or do you have to do some sort of dividing.
2^x = 1/8 = 2^(-3), so x= -3
In general, to solve a^x = k, you take log(to the base a) of both sides, which gives x log(base a) a = log(base a)k, as log(base a) a = 1, then x = log(base a) k. In this case you can see what x must be by observation as in earlier comment.
Will AS levels be this easy? I doubt it
When you know how to solve the problems it is easy, when you don't it ain't. Do as many past papers as you can. Good luck.
Thanks !!! But no calculus?
Not in Pure :)
how does k = 1/16 doesnt make sense
(8K)^2 - 4K =0
64K^2 - 4K = 0
4K(16K - 1) = 0
K = 0 OR K = 1/16
bro I regret picking maths 💀 this was very helpful though
Not a free ride!
Thankyou
Bro my mocks are in a few days
3:01 I don’t get it
But these are pure Mathematics 2 not 1
Will this get me from a d to a b?
Haha. It might, given that a car takes you from A to B!
