Thank you so much this amazing! You helped me get through my GCSE’s and now my Alevels, I can’t begin to explain how grateful I am for your channel 😊❤️
At 30:3, where did the 0.9825 come from? Because you said that the answer from part a)i) was 90.82951062 and I got that answer as well, so I'm really confused 😵💫
im a homeschooled a-level student and am supposed to be half way through differentiation but thanks to your video i've learnt all the concepts of it :). Imma go into class knowing everything lol 😅 but thanks for helping.
I'm not from England but I'm doing as level and these examples seem too easy, and its the same for most your A level videos, can you please do more challenging questions. Your videos got me an A for GCSE but since questions vary a lot in terms of difficulty on as level can you please do more difficult examples.(CIE exam btw)
bro just use past paper questions. And if you have a problem just go on youtube and search the same paper and question. Do this again and again until you master it
Hi Sir, Thank you so much for all these videos, they are very beneficial! I have a question about the modelling with the differentiation problem. At 31:09 I was confused about the 0.9825, where is it from (I substituted 90.8 and got a local minimum cost as well, however, didn't get the exact answer as yours- I got 0.004 - am kind of confused)?
The sketch is incorrect at 15 minutes in. It has an x^3 term, you have drawn a graph of x^2. The answer is still correct though, just that the gradient is positive in those regions, which it is not in the graph you have drawn. But thank you for the content, your explanations are really clear!
14:40 the question asks for increasing so it can't be including 0 as that's stationary, correct? I just got confused because he wrote 'greater than or equal to' rather than 'greater than'
Hi I am curious how does the +6 after 24x on the right side get eliminated? Thanks. Or is it because left hand side we divide by 6 so we also +6 on right hand side be divided by 6? Then +6 should be 1 right instead of disappeared
Your voice is so clear and kinda sexy haha, no but seriously thank you for going slowly on these questions and getting right to the important steps and actually using relatable questions that I can revise with. Helped me a lot with my uni mechanical engineering course
Amazing I’m so glad you are enjoying the videos! Such an awesome course you are studying I hope you are enjoying it! Would love to hear how you are getting on with it! 😁🙏🏼
I found some of his videos useful for this, the playlist starts with a line equations video and explains how normals and tangents work throughout the playlist, 3/4 videos in the playlist.
h gets smaller and smaller so the triangle used to estimate the gradient gets smaller. The estimate of the gradient gets better. As h gets as close to zero as you want it to. You can treat h as zero in the equation. The limit of h is zero.
@@doodlebob1898 A2 calculus is used from A1 calculus, but has WAYY more content and problem solving skills. This video will barely be enough for A1 differentiation.
Hi. You actually need very good indices skills for differentiation. Anyways, to answer your question, If u wanna shift x² to the top lets say it was 2/x² so that would become 2x^-2 right. Similarly, in this if u shift x² to top you would take away a power of -2. So, 1/2-2 = -3/2. Lemme know if it helps
