my p2 exam is today so this was extremely helpful as i kept forgetting the trapezium rule now that you have explained how we can get it, it got engraved on my mind thank you alotttt
Just a quick question, usually there's a follow-up question after doing the trapezium which says 'is your answer an over or under-estimate of the area', am I meant to just draw trapeziums and see if my lines go above (over-estimate) or below (underestimate) and base my answer from there or is there a method? Thank you for this!
It's about the shape of the curve. Wish I could post a 📸 . So if n shaped then underestimate, if u shaped then overestimate. Try drawing these two shapes now and one big trapezium, it should make sense.
@@MathsDeity ohhhh makes sense so like if it's a u shape, it's like filling a circle with squares, there's gonna be missing space. if it's an n shape, the trapeziums will slightly go out of bounds, so an overestimate.
I had planned FP units this academic year. However, external circumstances has prevented me for completely everything I had planned this year. I am only now getting back to a point where I can regularly upload again.
hello i have a question, not sure if youll see this but here goes, lets say on question three 15:04 i tried solving it on my own and in the table i put the numbers from 1-9 instead of adding halves. my answer however was different, it was somewhere around 3. why would this happen? im sure i applied everything correctly. also thank you sooo much for these, you don't know how much you if a help you are
from my understanding, you have to use the values between 0-4 as that’s what you are intergration from, using values that aren’t next to the integrate interval sign won’t get the right answer. I think that’s what it is, apologises if wrong
A half divided by 2 is a quarter. Hence 1/2/2 = 1\4. Alternatively, think of fractions in lower school. If you divide 2 fractions it is same as multiplying when the second is inversed. 3/5 divided by 4/5 becomes 3/5 x 5/4. Hence 1/2 divided by 2 becomes 1/2 x 1/2 = 1/4. Hope that helps as really hard to explain via text!!
If this channel wouldn't have existed, bye bye to my university life. I really appreciate what you do here. Thank you so much

@@MathsDeity btw, could u please cover more of s1? the exam is in 2 weeks so it would be helpful if u could cover maybe 1 or 2 more chapters
Thank you boss! Amazing work
Your welcome
Thank you! Tomorrow exam!
This was absolutely beyond helpful. You’re a legend. Will there be a FP2 playlist soon ? If not please reconsider you’re a life saver !!

@@MathsDeity Please do fp2 i know a lot of people doing it this jan. Would appreciate it so much if you can do it by then!

wait why would you go from 1-9?
@@amanimj5590 why not? we can apply any numbers (or so i think) as long as the difference is the same between each one

No probs 👍
sir may i please know how w/2/2 turned into 1/4 in 10:32
it just went right over my head and its stressing me out
