hi, can u also do Maths spec B paper pls :)

Hello, I have a very important question and really need a respond🫣Are the A Level tricky questions from youtube channel suitable for A Level Edexcel board??Wising everyone sunny and well deserved summer!👍

❤❤❤❤❤

Projectile question, part (b): K.E. lost = P.E. gained. Initially: K.E. 1/2 mU^2 and P.E. = 0. At max. ht: K.E. = 0 and P.E. = mg.10 = 980m. Therefore 1/2mU^2=980m., giving the required answer: U^2 = 1960 (m cancels). A far more appropriate method, that your students should be made aware of!

yoo mr astbury mot doing mechanics questions lets goo

I think it’s Adriano from Brazil and inter

why is the first question 2 marks bro, should be 3 ngl

before watching this video i had now clue about inequalities but now i feel more confident about them

In the last question, could we not have said that length AO = 13? AC was calculated to be root 194 with the same triangle. My answer was 61.5 as I said tan^-1(13/5root2) = 61.5. Any help is appreciated.

Simpler way of doing the regular compund interest questions is the formula (Question 1 for reference): 8500(1+2.3÷100)power 3 Answer is the same but confusion is cleared. (1-2.3÷100 if value is depreciating)

There is a more intuitive way to get the radius of the circle. At the point where the curve touches it, the gradients of the curve and circle are the same. Differentiate the Cartesian equation of the curve (implicitly). Differentiate the equation of the circle (implicitly). Set the two derivatives equal to each other and, after simplification, we get -2x=18x - 9x^3, reducing to 9x^2 = 20, hence x^2 = 20/9. Substuting for x^2 in the Cartesian equation of the curve, gives y^2 = 80/9. The equation of the circle is X^2+y^2=r^2, therefore r^2 = 80/9 +20/9 = 100/9, leading to r=10/3. I wouldn't say this is better than the first method you showed, but it is a lot more obvious to anyone getting to grips with all this for the first time.

Just did this whole thing in a day (except 21 topics I haven't studied yet). Thank you so much for this, I prepared WAY ahead of time.

Im in yr11 going into yr12 in september and planning to study a level maths and further maths. Is the calculator still worth getting even in exam mode? thanks

hiya mr what note taking app do you use for writing?

It's just amazing

thanks!

I've profoundly reached to professors of higher consultancy at university's of my mathematical hypothesises on ballistic ratio and Euclidean geometry further more quantum mechanics and hyperbolic geometry and equations

Much better doing the last part of the last question entirely in the RUN/MAT mode of the fx-CG50, as opposed to first using the statistics mode. Press the OPTN button and select CALC followed by SolvN. Next, press F6 followed by F3(PROB). Press F6 again and select P(. Now press the fraction key and, in the top box, enter 180-160. Go to the lower box and enter x. Get the cursor to the right of this fraction and select the = shown in yellow (SHIFT decimal point). To the right of the = sign, enter 0.8, and then press EXE, followed by EXIT. The calculator displays 23.763659, giving you the answer directly. Remember that on Casio calculators (even the inferior fx-991ES) P( is the command for P(Z<z) and R( is for P(Z>z). Both can be used with SolveN or Solve commands on the Casio graphics calculators, though I don't think you can concatenate with P( or P( on an fx-991ES!

Much easier to get the initial velocity of the projectile by using the path equation: y=xtan(theta)-gx^2(1+tan^2(theta)/2U^2 This can be done using the solve facility on the fx-991EX and gives the answer directly. (X=15, L-R=0 where X represents U).

thanks j cole u carried me in my as paper

I have my math GCSEs next year, and its great that i discovered ur channel early so i dont get cooked.

thank you!

Guys what do you think grade boundaries will be like ? 240 for an A* or higher ??

Thank you so much for all your help!

Goatsbury

thank you king🙏

I smashed mechanics but got cooked by statistics.

Q4 actually pisses me off, why do they just put 2 marks of that in 😂 straight up memorisation at that point

🐐

The goat carried my A-level maths grade

I didn't peform really well because our international school do alevel in Beijing which is about 7pm to 9pm but I am glad that my efforts I put in didn't fail. Absolutely smash the mechanic questions for sta i am pretty suer i only lose about 10 marks? Again, thank you sir for those amazing videos! Keep doing it and help the next y13s.

The series on the 50 hardest questions was absolutely clutch!! Made doing loads of maths actually bare-able going through different topics in each one! Plus your predictions for the applied paper came in so handy, i felt like it prepared me for really hard questions so when the questions that came up in the exam that were relatively straight forward in comparison it made them so much easier!! Thank you!!

thank you so much throuhout the year! your past paper walkthrough has been amazing. Thank you so much

the goat

Sir thank you so much for all the walk-through and tricky question videos😊

You're videos really helped me so much Mr Astbury, I can't thank you enough!

To simpilfy your integral and intergrate 1+×2-e-³×==S 1/4 dy = 1+in +x²-e-³×

E-3× (2×-3ײ)=×e-7×(2-3×)=×=2-3×)/ex³x=ex³ dy /e7x +e 3×=4-1=1/4 S 1/4 dy = 1+in x²e-3x+c

I love you - your the best man I know. The fact you have motivated and kept me inspired is unbelievable is top. I will stay subscribed no matter what and spread your name! Xxxx

Thank you so much for your help!

Thank you SOOO much for all of your help for my A Level maths. I am confident I got over 95% in both paper 2 and paper 3, most of which is purely because of your videos, especially paper 2. I've been watching you since March and your videos have been absolutely amazing!! I will absolutely stay subscribed to you, and when my brother does A level maths in a couple years time, you will gain yourself another subscriber, and in fact I will be recommending you to any person I meet doing A Level maths! Once again, thank you so much, and good luck with all of your endeavours sir!

Sir is this on the large data set

I love you man, the work you do on this channel is just spectacular. I wish you all the very best in life

Thank you for not making grade boundary predictions. As you said they are often a surprise so predictions are pointless.

Gained me at least 10 marks thank you so much!

You are the GOAT thanks so much for your help, and yeah, wtf was that England game 😭😭

Love you 🐐
