Has this video been made yet ? ( just curious )

[@maykalu4554]

Thanks really helped

[@lizavoloboeva3500]

Hello, thank you for the great video! For the mechanics question why do you not resolve diagonally and only vertically or horizontally, ie Ncos(theta) + Y = 20g rather than N + Ycos(theta) = 20gcos(theta) + Xsin(theta) where you split the friction force as in other inclined planes questions?

[@BicenMaths]

So you could do it that way if you wanted to, but you’d find your calculations becoming very complicated as there are many more resolved forces. In general in these types of equations, up and down tends to give the simplest calculations! Hope that makes sense

[@IceHockeyCreamer]

The mechanics question was not too bad in my opinion. I think the main reason why mechanics can be so difficult is because it’s a bit more ‘practical’ compared to pure maths. The math is easy (apart from the math in FM2 lol) but it requires a lot of visualisation of the question i.e where all the forces are acting, how far is the particle going to travel up the slope etc.

[@BicenMaths]

I agree! Once you nail the visualisation, it all falls into place - I like your take on this!

[@amyhuang6575]

please do another one these!

[@jamespeter570]

I’m sure question number 3 doesn’t make any sense. Summing from x=4 to x=9 suggest there are only 6 terms in the sum meaning that the sum should be 0 as it’s a finite sum and each term goes to zero. Obviously this is meant to be Riemann sum which converges to the integral but the formulation of the question is shocking

[@viguswg]

Gl to everyone doing A level maths tmr

[@katozrippla1497]

Number 3 is actually an entire topic in the Edexcel A Level Maths textbook. It's the last section in year 2 Integration, named "Integration as the limit of the sum"

[@fatmabatmaz2]

I think they added that to the new version of the textbook after everyone complained about it being on the exam and not on the spec

[@BicenMaths]

So would you be if you had to do these questions 😂 😳

[@nevzys]

You should make one of these for Further Maths A-Level! The textbook questions simply do not match what they ask in exams and it would be nice to see your thought process. For example, in the 2020 A-Level Edexcel FP1 paper, "no-one got full marks" (from examiner's report) on the last part of the last Q!

[@BicenMaths]

I am hoping to make one for FM in the near future!

[@tomfarrell1933]

23:35 Why would the normal reaction force be acting in a different direction if there was friction? I was under the impression it was always perpendicular to the point of contact.

[@BicenMaths]

Good question! You are correct that the NORMAL reaction is always perpendicular to the surface - this is the surface “pushing back”. But the reaction force here is the combination of this normal force, and a frictional force which will be perpendicular. “Angled” reaction forces only come up in moments in mechanics as previously our forces have been points, not lines, or rods. Rather than thinking of the reaction in the question, instead consider the reaction of the end of the rod on the floor. It experiences two things - 1) the floor pushing up 2) the friction pulling along parallel to the floor. It is the combination of these (through Pythagoras and trig) that means the reaction will be at an angle. This is partly why I think this question appears in the Top 5. Many people think reactions can only be normal - but sometimes they will be angled. Hope that helps, let me know if not and I can try and explain more 👍🏼

[@MichaelHenderson1948]

That integral using the Sigma notation, upset all the candidates where one of mine went, though the FM people knew what it meant. However, from what I was told, the Chemistry paper reduced several students to tears, while less was said about the Maths.

[@BicenMaths]

It seemed unkind to do something they knew would be unfamiliar - it throws students off so much! And if you know... then it suddenly becomes so easy. Tears after exams - a teacher’s worst nightmare!

[@MichaelHenderson1948]

@@BicenMaths Yes, she said that no-one in her class had known what to make of it. The sad thing was that the most experienced science teacher had left during the year, and my g'daughter had to learn some of her chemistry by herself, just missing by 3/400 that all-important A*, which cost her her place at Cambridge. The maths was all right thank goodness. Now the younger sister has to self-isolate for 2 weeks because of someone in her class. And this is Yr13.

You had to integrate the line and find some unknown in the line (it was like y=x(kx-8) or something similar to that). I was lost and 98% of people were. I repeat, the average was 2%, 0.06 out of 3.

In q10, the mod graph has its minimum point to the right of the y axis. In what way is q4 difficult?!!

[@joeclayton6973]

Hi, I am having a bit of trouble with the integration as limit of a sum question. The way I am imagining is there is every y value from 4 to 5 multiplied by a very small width delta x creating rectangles, but I thought sigma goes up in 1s each time so there will only be a tiny rectangle at 4.0,5.0,6.0,7.0.8.0,9.0 and no decimal value between which will be a small part of the area, so how does that notation show that there are infinite strips. Thanks!

[@BicenMaths]

So you’re right that sigma goes up in 1s, but this is a discrete measure. As we move from discrete sigma to continuous sigma, all the values in between are included. If you want to know more, check out 3blue1brown’s playlist on the essence of calculus, it’s amazing and explains it all in much more depth!

[@joeclayton6973]

@@BicenMaths Hi, thanks for recommending those videos they were very useful! So am I right in thinking that sigma goes up in 1s for sequences/series because it can only work for increments of 1 but when using sigma for integration it covers all decimal values in between.

[@BicenMaths]

Yes, in a nutshell!

[@JohncTrumpet]

@@BicenMaths The notation is simply wrong though. The index of the sum is always "discrete" - maybe better though of as indexed by some subset of the natural numbers. Otherwise what does it even mean to sum over an uncountable set? Summing over infinities larger than Aleph null can be defined but certainly not for A - level! This question (qu 5) is very badly poised at best. The integral symbol should be equal to the infimum of upper Riemann sums and the supremum of lower Riemann sums where one considers all partitions of the interval into n subintervals... I don't understand what you mean by discrete measure? Are you referring to measure theory?!

[@BicenMaths]

[@marxcarton3858]

hi sir, for (12:19) question 10. i. Can't we say z is any number and then say (n^2+2)/4 =z, now we make n the subject, n=√(4z-2), this is equivalent to n=√(2) * √(2z-1) when factorised. And since √2 is an irrational number we can say multiplication of an irrational number to another number would give a real number in fractional form thus it cannot be a natural number.

[@BicenMaths]

But if 2z-1 was equal to 2, then you would have that n = root2 x root2 and so is 2, which is a natural number! So this proof doesn't quite work.

[@ginevrasaraconi8916]

Hi, would you be credited for using proof by induction for n4?

[@BicenMaths]

I’m not sure we can use proof by induction to show that something is NOT divisible by 4. Only to show it IS divisible by 4.

If you draw a line vertically down from C, you have a large triangle. The angle at the top is 90-theta. Using more angle properties, and this angle, you soon work out that angle is also theta! It’s because of breaking things down into vertical and horizontal components. Try drawing it out and filling in missing angles - it should make more sense!

you started with the reaction force of acting perpendicular to the floor and labelled it y then later added another reaction force at a slant, why does the reaction force not act perpedicular, I though that was the whole point?

A reaction force at a peg will be perpendicular to the rod/beam. This is because the circular peg, when pushing “normally”, is perpendicular to its tangent, which is the same as the direction of the beam.

@@BicenMaths Thanks for the encouragement what would you say are the hardest topics on the course ?

[@BicenMaths]

I would say Year 2 Integration - not because it is hard as an actual topic, but because it relies on SO many other chapters. If you don’t understand all of the maths up until that point (especially trigonometry and differentiation) then integration becomes really tough. So it’s nothing to be scared of - just something to prepare for! I also think trigonometry is generally agreed to be a tough topic. Have you seen on my channel that I have videos for nearly every chapter, exercise by exercise? It contains all the lessons I teach my students, recorded live.
