[@HappyEmileHeskey]

I've followed your videos from GCSE through to A2 and they are by far the best maths videos on KZbin. Crystal clear explanation in this one! Thanks very much!

[@ExamSolutions_Maths]

+UJMedia Thank you for that and any support you give.

[@pinkmangooooo]

What u do in life now haha im currently in yr 13

[@subtilizer8907]

I am a college student in an American university but i did edexcel math AS in my high school. I used to watch your video's and they helped me and my friends alot and even until now, sometimes I don't get what the professors who teaches me (Calculus 1) in my college are saying so i return back to these video's to understand. I hope you will contiune this work.....Thanks for everything, still helping me even after high school you are a great teacher !

[@jessiechampagne9690]

I finally understand implicit equations! thank you so much! I have been struggling with this for a month now and I feel like a huge weight has been lifted off my shoulders

[@ExamSolutions_Maths]

+Jessie Champagne Excellent.

[@chickennuggets1837]

11 years later and it's just as relevant

[@ExamSolutions_Maths]

Thank you

[@Miru_Man]

it all makes sense now! Thanks!

[@ExamSolutions_Maths]

That's good to hear.

[@DipenTiwari]

Why aren't there more teachers like you in this world? You are awesome. Thank you so much. I have my IB Maths HL final exams tomorrow and you help me revise so much. Thank you once again.

[@viralfooty4844]

What the heck, the way you taught this you made it seem so easy.Thank you for your commitment to help maths students to do well in their exams.

[@ExamSolutions_Maths]

Good to hear you have it sorted now

[@Nigahdaasht]

The best Explanation I heard off ever

[@ExamSolutions_Maths]

The aim is to find dy/dx. Whether the x ends up on the top or the bottom depends on the equation. In this one it fell out on the top.

[@shafayhaseeb8476]

Sir you are great..... I wish all teachers explain like this :D. Keep up the good work..... GOOD LUCK!

[@harrisonbennett7122]

This is so useful, thank you.

[@Shinoda908]

Thanks for this I personally find this to be one of the harder chapters in c4, and this has proved to be very useful so again thanks

[@ddodjg]

Is it fair to say this is pretty much using the chain rule but assuming (atleast for the second term) that the x term is 1?

[@jevonXman]

your videos have been the most helpful videos I could find on the net. truly you are awesome at your craft and know well how to educate. i have used these to Pass College Algebra for my major Electronics &Telecommunications technology, done engineering math 1,2, and now doing 3. and this tutorial is really helping me to understand so i just wanna say thank you for making these tutorials. God Bless

[@anujchaturvedi6296]

Very Good Tutorial 👍

[@angelstarfire]

Thank you! I get it now!

[@arabido]

You use it in your C3 paper videos. I think this causes confusion as to where the tutorial actually lies. I myself had to find it through searching on youtube. Thanks for all your help by the way. I'm broke as hell at the moment, but the second I can, I'm definitely going to donate. Your aid has honestly been priceless.

[@thehh5118]

When you do d(5y^4)/dy.dy/dx wouldn't the dy's cancel out leaving, 20y^3/dx? Why does it form 20y^3.dy/dx?

[@ExamSolutions_Maths]

+The Hh With limits, in calculus that rule does not hold.

[@joanneaa3241]

+ExamSolutions could you please elaborate on this? or do we not need to know why the dy's do not cancel to form 20y^3.dy/dx for A level maths? because I'm guessing that limits is degree level stuff. Thank you :)

[@Ogiiishred]

best teacher ever

[@calumyoung7172]

very helpful video. thank you. amazing how many times this has been watched, and how many maths a levels it has contributed to. thanks.

[@tinashemangumba1169]

thank you so much ....made easy to follow through

[@oohmyyy]

but when you do d/dy multiplied by dy/dx wont that give you a result of d/dx as opposed to dy/dx?

[@ExamSolutions_Maths]

oohmyyy d/dx not dy/dx

[@TheMtahir786]

plzzz help me with this problem: Q. Define implicit function x^2y+xy^2+x^2+y^2=0

[@henrywardell723]

you are doing gods work

[@ExamSolutions_Maths]

It is correct. Just multiply top and bottom by -1 and you have my answer.

[@Whizeplays]

oh right thanks, just wondering if I put my answer instead of yours would I be penalised?

[@Intrdmnsion]

Thanks so much! I was having trouble with implicit differentiation until I saw this video.

[@vortexuk]

Legend! I knew how to do it but didn't completely understand the theory behind it, this helped a lot. Thanks :)

[@ExamSolutions_Maths]

Excellent. Best wishes.

[@aftab7471]

can we define implicit equation as; it is an derivative of as equation in which we deal with two variable x and y, in which we differentiate the equation w.r.to x ??

[@productivity7587]

[@sameur96]

could you go over the the other examples with trig and exponentials shown on your website?

[@Sentoefn]

You made this so easy. forever my go to page

[@revatikotwal7105]

Sir thank you so much. You're work is simply amazing .

[@ExamSolutions_Maths]

+Revati Kotwal Thank you

[@shayma3358]

Can someone please explain the difference between dy/dx and d/dx. I know that dy/dx is the derivative of Y with respect to x and d/dx is the derivative of x. But what does that rlly mean? Maybe I'm thinking there's more to it and their isn't but I feel like I need a better understanding of it.

[@RDW1216]

very helprful

[@daemonk9]

thanks so much for this tutorial.however it looks like you forgot to update your website with it, presence of mind had me looking for it on youtube!

[@productivity7587]

Thank you!

[@barakshp85]

Thank you, just to clarify, at the last row when you present the answer, why the xis not in the same row of dx? does it matter as a solution? Barak.

[@ExamSolutions_Maths]

Good luck with your exams.

[@nashabennya3037]

thank you for the knowledge,sir. been following your video for my own revision and it really works!

[@ExamSolutions_Maths]

Thanks for watching and I hope all the other videos offer some help.

[@luckyim6504]

By the way, what is the difference between derivative and differential? Is derivative just d/dx And differential is just dy/dx

[@kaijoseph3629]

Brilliant video! But there are some questions in my text book which ask to to find the interval of possible values for x and y for implicit functions which are curves. Is there a standard method in finding these intervals?

[@robindragirl]

Thank you so much! I would have failed in maths exam without this.

[@ExamSolutions_Maths]

Fariha Tabassum That's okay. Pleased to hear it helped. Thanks for using.

[@sabrinaloves1D]

does it matter which side you put dy/dx when grouping them together? I would've moved mine to the left side to give -20y^3dy/dx+3dy/dx but this gives a different answer.

[@ExamSolutions_Maths]

+Sabrina Haris No it doesn't matter. If you did not trip up on the later stages then your answer will be mathematically the same as mine if you multiply top and bottom of your answer by -1.

[@siareebye4742]

thank you so much

[@haribol212]

epically explained.! 👏🏻 Great work sir, Keep it up!

[@Whizeplays]

ok thanks a lot!! real fan of your work, appreciate everything!!

[@timk8079]

Excellent

[@ExamSolutions_Maths]

@daemonk9 I have just checked the website and it is up under C4 or am I missing something.

[@Whizeplays]

is there a reason why you brought the 20y^3 to the right hand side? because I didn't and I got a different answer....

[@ayyyzma2937]

This is a great explanation! Thank you!

[@ExamSolutions_Maths]

Thanks for your support.

[@EE-Spectrum]

Is there a counter part for integration which involves x's and y's?

[@ExamSolutions_Maths]

Interesting question. The closest thing to what you may be thinking of as 'Implicit integration', would perhaps be exact differential equations.

[@EE-Spectrum]

@@ExamSolutions_MathsThanks very much. I appreciate this, but separating the variables in differential equations is very challenging.

[@maxhuguet6735]

I feel like neo once he starts viewing the matrix as just numbers. helps sm

[@alicesMUUSIC]

Wow this has been a massive help thank you!

[@TheRealShaiLamar]

Thanks a lot; this was a great help

[@JuiceBoxBoiii]

You are a life saver.. test tomorrow :"]

[@ExamSolutions_Maths]

Best wishes

[@JuiceBoxBoiii]

Thank you exam solutions! I did great on my exams because of you

[@584emad]

sir. if we don't write the dy/dx in the exam then would that be acceptable ?

[@richcheema]

+thenycfilmer loool savage

[@Enigmo1]

Okay so it's quite simple now. But what module is this mostly used in? C3?

[@lavarball61]

and c4

[@Dan-bg5fm]

c4?

[@tomkrys3331]

Seems so simple when you explain it

[@ExamSolutions_Maths]

Cheers

[@Ahmed6941]

how do u solve this equation : x^2+y^2-4xy+3=0 please help

[@finlayhumberstone8137]

Amazing help thanks

[@luckyim6504]

Omg it makes so much sense!!!!!

[@marymancinelli5790]

what happened to the 3y? why did it only become 3 dy/dx?

[@luth495]

This is amazing!

[@Whizeplays]

I got 14x-3x^2/ 3-20y^3 when I kept the dy/dx on the left hand side

[@safwaniqbal2046]

what if i have xy together in an equation?

[@ExamSolutions_Maths]

Use the product rule as in this example kzbin.info/www/bejne/sJeweZ9rbLd1Y8U

[@daemonk9]

@ExamSolutions yeah ok i see it, I got sidetracked by your comment in the implicit and parametric equations section, that you didn't do a complete revision guide for them as yet, straight to google after that.......

You and Prof. Leonard are the best teachers. But my god the mouth noises your mic records.. aahhhh!!!

[@gurukilla]

i tried to do this before i came to this video and done it the same way but i still got it wrong the fuck?

[@ExamSolutions_Maths]

No reason. You should still end up with the same answer. What was your answer?

[@kingezaby7241]

Sorry Mr Edward Did it 1st ♥️

[@ella-gm6bz]

lmao ur the only reason im not failing a levels

[@ExamSolutions_Maths]

Best wishes.

[@ibrahimshabaz5074]

That is an extremely 'easy' question though when you take into account implicit differentiation. There are much harder ones which would require easier steps that you should think about going through imo

[@ibrahimshabaz5074]

*Which would require more steps

[@ExamSolutions_Maths]

Not at all.

[@Therysin]

Use product rule and separate, u=x v=ln y. Then differentiate implicitly. Good luck!

[@rosehathaway9129]

wow you make it so easy, thanks!!!!
