Patrick you're doing amazing work with these walkthrough videos... you're ability to talk questions through simply is really engaging and so different to some of the other faceless channels out there. You've hit the nail on the head with giving people value for free as you've got me hooked on AITutor too... Keep up the good work you're helping a lot of people.
37:42 Hello! I’m slightly confused about the modulus here. You said that the modulus of r is 1/2, but I assumed it would be 4 since it sets r = 4. I don’t really understand why this is the case, any explanation would be greatly appreciated!
Oh, never mind! I think I get it. r = 4 does not represent the common ratio, it is the first value to input so that we can get the first term. I need to find the second term to work out the common ratio. I think i got confused because they used the letter r (which i assumed meant common ratio) in the first place. Is that something that they do to trick us, or do they use 'r' every time?
I intend to keep the promise! I've just wanted to prioritise getting some more past papers out due to the revision period, as well as being busy creating the AITutor GCSE course. It'll be here soon I promise you that!
@@AITutor ok thank you :). Will it be done before Monday 😂- mocks r then. If not it’s fine , still got some mini exams in may. Will it be done roughly before may the 14th
Hi, For Question 14 I’m confused on why we are able to just replace 3 constants with a single one. In part A, we have stated that k=c+8. Since we know that the 8 exists, why can we still replace it with another constant when calculating part c. Could you elaborate please ?
Because c is a constant and 8 is also a constant you can just write c+8 as one big constant k. Technically you can substitute c+8 instead of k and you'll get the exact same answer. Its just easier use to k instead of c+8 and it's neater.
For question 11, why cant u use the power rule? (my backup plan after not knowing how to use the logs) [a^x differentiates to ln(a)a^x] So i thought u could say dy/dx =ln(x)x^x Therefore x =1 because ln(1) = 0. Its incorrect but idk why
I didn't write out every term, only the first few and the last couple. The term before that (for n = 46) would have had a log48 on the top, cancelling with the negative log48 from the next term 🙂

Best exam walkthrough out there.
thank u for going through each question in detail unlike other channels!
I like your approach in conceptually having an over view of the problem and gradually mathematically homing to a solution.
Will you be doing the Edexcel October 2020 papers walkthrough? These videos help a lot!!
Thankyou so much for these past paper videos! Can you do any more videos? They help so much!
For 8 ii why can't you use the arithmatic series equation with the first and last term?
I really like your video and teaching style, good work!
Such an amazing teacher, keep up the good work
f me probs the hardest a level pure paper
fr
Disgusting paper
@@zigzagnemesist5074 imagine we get more disgusting paper xd on tuesday
@@itzdimi7569 I wouldn’t be surprised, they seem to be making the exams harder every year
I am cooked seasoned burned finished marinated finished 💀
Wow, this is super useful, I'm on year 11 but planning to do further maths, this will give me a good idea of what A-level maths will look like
Doing further maths will be the best decision you can make! I'll be putting out more GCSE content over the coming months too 👌🔥

wow so helpful!!
quick question
for 7D where did the 2N come from?
Each bar of soap costs £2
question 5 isn't delta x?
ill thank you after my mocks my guy. what a lad. what happened to u doing the hardest qs vid. didnt u promise me you would do one :(

Definitely before May 14th, definitely not before Monday 😂
yes rags
@@vrajshah6323 Ready for tomorrow?! Hopefully this AI tutor guy makes us a bomb! 🔥. Nervous
hi do you think you will be adding further maths by next academic year?
For Question 10, why can’t ON= OA +1/2 AB + Y (CM) ?
for question 8, what do we do if the modulus of x is not below one to work out the sum to infinity?
This is such a good video! Thanks man, helped alot
Good to hear it man, nice drumming! 🔥
Can q7 be AS level too?

So i thought u could say dy/dx =ln(x)x^x
Therefore x =1 because ln(1) = 0.
Its incorrect but idk why
i think it's because a is a constant whereas x is a variable
@@medievalrat324 true thank u!
@@wippo42 good luck tmrw!!

How does the log48 cancel?
I didn't write out every term, only the first few and the last couple. The term before that (for n = 46) would have had a log48 on the top, cancelling with the negative log48 from the next term 🙂
@@AITutor oh sweet , when is the 2020 walkthrough coming out
Nice work ❤
