Hello sir, paper 1 was unfortunately disasterous i am only confident about 9 questions but anyways.. really appreciate these.. but for the euler method question how can we do it on the gdc recursion mode

[@GingerMathematician]

Hi Hazaard sorry to hear about the Paper 1; I haven't seen the IB papers but let's focus on Paper 2 👍 For Euler's Method (such as the video here kzbin.info/www/bejne/iJDWgJJnotupbMU) I use the graph function on the TI Nspire for the recursion mode, do you have a CG50 instead? Do you mean the A value for the question at the timestamp?

[@vHazaard]

@@GingerMathematician Yes i have a CG50 and i have watched that vide of yours thanks a lot however for such a question i guess we have no solution but to do it by hand... also based on the topics that come on apper 1 below. may you please give a slight prediction of what topics to foucs on.. i will be focusing on eulers, eigenvectors, and 2nd order differntial equations and im sure a voronoi diagram will come along those and maybe optimization... but i really need any advice perhaps.. a position vector question may also come up on paper 2.. heres the list of paper 1 qs and topics today: Two way table Probability with replacement An upper bound lower bound calculation for arc length and we were told measurement is only accurate to 1 sf then asked to find percentage error and justify which is highest between the lower and upper bound A finance question but with functions? 5 marker geometric sequence: We were told u2 is 4 less than u1 and we’re told the sun inifnity geometric to be 9.. then asked for the 3rd term “with justification” Type I Type II error Very weird format... 1 variable test Cubic regression line equation and simultaneous equation ->find whole values of a, b, c Trapezoidal rule Integral area Finance( r-i, inflation.. real value, etc) Trigonometry Inverse function and then intersection of the inverse and the original function : ln (1/x-2) A 2 mark question on position vector given a sin and cos squared coordinate somehow and asked to find velocity vector A very unique complex number question Re(sin(t)^2) + Re (cos(t)^2) And 2 questions I barely got to attempt :( Context of the question just in case others did it and remember: a snail question involved with area and integral (seperable differential?" etc and a maximum voltage question

Thanks, are you looking to create any IB content?

Great video as usual!

Thanks, hopefully this will help students with the new IB courses!

great job friend, this is very helpful

Your videos are great 👍

[@GingerMathematician]

Thank you 🙂👍 Not much out there for IB HL AI so thought I would make a contribution!

[@salomithetutor8180]

Keep up 👍👍👍

Thank you 🙂 Are you taking IB HL AI?

[@Abcdeee_p]

hey, paper 1 was great and a big part of the reason was your video showing the steps for the may paper. Left a few sub parts but still very confident. Every time I try to attempt a paper two I loose focus when I find one of the sub parts tricky and feel demotivated and unable to complete the rest of the sum. Any advice?

[@GingerMathematician]

Hi Abcd glad you enjoyed the Paper 1 walkthrough. For Paper 2 really maximise your marks on the topics you know - if you understand optimisation well then ensure you get the full marks on that question. ALso if you find a sub part tricky, go onto the next question and let your mind sub-consciously think it through so you can come back to it 🙂👍
