Equations & Inequalities in less than 20 minutes • A-Level Maths, Pure Year 1, Chapter 3 📚

[@user-tw1nr3tv7p]

At 18:53 aren’t you supposed to use the intersection symbol rather than the union symbol? Because we only want the intersecting area and not all possible areas of all equations combined(which is what union symbol means right)?

[@BicenMaths]

Yes, that is correct! Good job we didn't need set notation, I would have done it wrong! I'm pinning your comment. Thank you!

hi sir you are smashing it with these videos thank you!

[@rKaraa]

the timing with these videos are perfect, also are you going to be this for the wole of Pure year 1? thank you

[@BicenMaths]

Yes, hoping to complete them all for Pure Year 1 and 2 - they take a lot of time to plan, I write all my own questions for them, and try and make sure they fit the challenge level of the exams, too!

[@lucyjones9903]

You are genuinely my saviour, these videos are great for revising quickly pls keep making them 🙏

[@chaska8144]

a good addition, sometimes the playlists can be long for a chapter that doesnt require too much attention if you've revised it before so itd be tedious

[@BicenMaths]

Pleased to hear this! I felt there was this gap on my channel, so trying to have it so there's something for all occasions of mathematical studying!

[@AdamRyder-j1w]

I've been struggling with inequalities since GCSEs, thank you so much!!

[@BicenMaths]

You are very welcome :) Good luck!

[@jodiali8002]

[@BicenMaths]

Great! Thank you! :)

Hello Mr Bicen, May I ask that we please have these videos in a playlist, please ? - one for Pure 1, another for Statistics 1, etc. Thank you

[@BicenMaths]

When I have a few more videos I'll figure out how to organise them best - for the moment they are in the Summaries playlist, which is featured as one of the first sections on my channel homepage! But I will definitely arrange them into other playlists soon. Thanks!

Given Two general equations for finding the value of "x" and "y" 1) ax + by = c 2) px + qy = c Here (a,b,c,p,q are REAL NUMBERS) Can we write (ax+bx = px+qx) ( substituting the value of "c"and "c" is REAL NUMBERS like 0,1,2,3..........) Is it correct or not Please help with example 🙏🙏

[@BicenMaths]

@@rkm823 Yes this is correct!

​@@BicenMathssir here Two equations for finding value of 'x' and 'y' 1) ax + by = c 2) px + qy= c if "he substitution the value of "c ". (ax+by=px+px) It is not correct because he wrote "qx" in the place of "qy" . "If I am wrong please help to understand"🙏 🙏 I hope you help me

[@BicenMaths]

Yes I misread it. There should be y with the b and q!

[@chris_adu]

Your videos have been really helpful, thank you sir

[@sloco8284]

if it was kx^2 - 4x - (k+3) would the value for c be -k-3? as i would have expanded the brackets to get this or would it still remain as k+3

[@BicenMaths]

Correct, the value for c is -k-3, which is equivalent to -(k+3)

is this for edexcel?

[@BicenMaths]

Yes - any exam board, really!
