Sir can I use Canon F-789SGA calculator, or something else Pls reply Sir

Thank you so much sir 🙏🙏 Sir math optional ka strategy video plz share kare eash youtube channel Self preparation se kese ache mark la payenge plz guide us sir 🙏🙏

I think, this method is less time consuming A = (b1 - B - C)/ a11 : B = ( b2 - A - C)/ a22 : C = ( b3 - A - B)/ a33 feed this in the calculator and input A0,B0, C0 and press CALC. This also use improved values in next iteration as soon as it is available.

Very useful sir. Please continue this series

Sir we need more videos. Your videos are actually clearing our doubts. 🙏💯

hello sir, can you confirm that there wont be a question on interpolation on unequal intervals, as i find no mention in syllabus and no previous Q since 2013

Sir it's very helpful 💯. Thank you 🙏

in this, in formula we can directly use =-1/5(16-B1-A3) & =-1/4(7-B1-B2)( instead onlyA that you used ) and rest process same, this will ensure A will always represent 4th iteration and B will represent our K+1th iteration , what you think ?

This will help in finding value of function at some z, but how it is helping in residue calculation ( say zdz/(z^2+4z+1)^2) or integrability because both d/dz and integration is not allowed in complex option in calculator

This in paper 1... So can we use calculator in paper 1 as well

@28:50 did someone checked P-1DP , I am getting different

@3:40 the question has 3 subpart so maybe 1st part is having 5 marks , so directly writing by calci may not fetch marks or just manually doing the calculation ..2-3 step and verifying it via calci is better? what you suggest

Can you please share your timetable how did you manage maths+gs. Complete timeline. Thanks.
