OMG YOU JUST SAVED MY LIFE ! I WAS VERY FRUSTRATED BECAUSE I DID NOT UNDERSTAND WHAT MY PROFESSOR WAS TALKING ABOUT. THEN I WATCHED YOUR VIDEO THANKS YOU !
I really like you videos, I was predicted a grade D at GCSE, then my teacher showed me your website 2 weeks before the exams and I shocked my friends with a B! Thank you, I'm now doing Pure and Mechanics at AS Level and I'm pretty confident in getting a good grade in January exam. =)
you said that it is different when the curve goes under the axis. What do you have to do differently? love all your videos, ive had straight A's in maths since i found your vids and you explain everything better than school teachers
I have a question sir or anyone. when we find the integral of f(x) in a region I know we are finding the area. But How do we know that this is the region bounded by the x axis? for example the question he is doing at 4:26 how do we know that's not going forever down or rather stops at the x axis?
Go to Edexcel C2 index. Look under integration, area under a curve and then page to the 2nd tutorial in the series. Sorry, but UA-cam stops me from pasting in the link.
hi, i was wondering whether you have/could do a video on integration of a curve bounded not by the x-axis but by a line of y, such as y =1. would you integrate f(x) including "minus" of the y co-ordinate which axis bounds the area?
I had a question similar to this expect they didn't give me the interval and I was wondering how you find that? Do you just graph it and pick the points on the x axis?
I am still stuck with working out this question below, if anyone can help me i will appreciate it alot find the area between the curve y=(5x/2) - (5/x) and the x axis in the range x=1 to x=3
GoodEvening Sir. I am still confused with my answer. I need to Find the area bounded by the curve y=x^2+1 and the line y=x+3 (solve in two ways) hope you can help me po.

my favorite help math
channel, your explanations are great and really stick!
I need a tutor like you :) :) saw that question on a exam pass paper and dint knw what to do thanks :)
Awesome integral series! Concise, clean and understandable, thanks for these videos. 👍🏼👍🏼
You know how to say the right things. Thank you.

Pleased to hear that it is starting to make sense.

@heavymetaldeath4life That's very encouraging - well done. All the best for January. Oh and please thankk your teacher on my behalf.
how did you get -4/3? becasue i keep getting -2/3, and so surely [1^2/3 + (-1) ] isn't = -4/3 can someone please explain! thank you

@Yingk3 Yes I am happy to make a video. Just make a donation and ask me to make the video.
Pleasure.
thank you sir
you helped me a lot
I had a question similar to this expect they didn't give me the interval and I was wondering how you find that? Do you just graph it and pick the points on the x axis?
thank you so much sir :)
Yes, set y=0
thnk u . big help from u sir
You're welcome, thanks for using my work.
thanks
Y din't uh prefer the method of doing seperately frst 0-3 then -1 to 0 then add them up????....plz rply
Set y=0
I don't understand how you got 40 / 3 at 4:22. Can you please explain?
12+4/3=40/3
i need to find the co ordiantes of the x axis, how do i do this
You get negative answers. I have video tutorials on this on my website. Have you not seen these?
I am still stuck with working out this question below, if anyone can help me i will appreciate it alot
find the area between the curve y=(5x/2) - (5/x) and the x axis in the range x=1 to x=3

HOW TO FIND THE AREA OF a^2x^2 =y^3(2a-y)
wow, i did not see that there were multiple pages to each topic
no, i didnt see any? Im on the Edexcel board so i have been going through each topic in your edexcel list.
My akh

Thankyou
