- In this video I show you how to differentiate various simple and more complex functions. We use this to find the gradient, and also cover the second derivative. *Mistake at 5:43 - can you spot it?*
Enjoy!

How many of you’ll clicked into organic chemistry tutor and came back to this video cause it was too advanced
me
😅✋️
Dude 😢 how did you know
I came from periodic motion, physics
😅 how'd u know
You are the very first teacher i hear telling why we differentiate ! Thank you. I think i got it finally. Differentiation gives you the gradient at any point along the graph.
It gives u the slope of tangent line and secant lin e I am also 9 TH grader
Yeah, it's easier to understand once you know why in the world you do it
No kidding, that simple explanation went a long way. Thinking of it as finding the gradient really filled in some blanks, instead of just learning how to differentiate.
Next stop, limits. Is it just me, or does everyone learn more off TH-cam than in actual class.

As a complete beginner, this helped me get going with differentiation. Good video.
I have a calendar with nice pictures accompanied by different wise or thoughtful sayings for each day and this video vaguely reminded me of the saying for the day from a few weeks ago. It was when Einstein said "Genius is making complex ideas simple". Except I would adjust what Einstein said to: "Genius (teaching) is making complex ideas (clear and comprehensible)".
I've seen a few examples of genius teaching on various TH-cam videos and THIS video (for which I'm most grateful) is one of those examples.
Thank you that's so kind!
A few days ago I sat through a lesson on differentiation without really understanding what on earth any of it meant. Thank you so much for this simple and clear explanation, I feel like I’m now mostly caught up on the things I was confused about.
Same I Didn't understand all I heard was dy/dx
Thank you I have my exam in 5 mins
I’m now in a med uni guys 😂
Oof. How'd it go?

Press F to pay respect !!!
Very great
I have mine in 11 hours...
I learn nothing during my 2 years of Higher Secondary and here I learn in less than 10 minutes. Brilliant.
Glad you found it helpful!
this is the first time I actually understood GCSE math fully you're an angel!! you actually made math fun.
Literaaly one of the most well broken down maths video i've ever seen. It really helped a lot. Thank you
Hii ..from where u r?
5.28 there is a mistake. the answer would be: 5x^3/2 + 2x^-3/2
Solution: th-cam.com/video/5Eh9h_ryyJY/w-d-xo.html
I was looking at the comments to see if anybody noticed that! anyways, that means we all make mistakes and mistakes are ok, but hopefully she corrects it.
Thanks for the answer
Thank goodness. I got the same answer as you but thought I was wrong and couldn't find my mistake. Glad you wrote this comment. I was going to ask too
Yes on the last equation
um guys no, what she wrote is correct, the finals and is -3x^-5/2 + 2x^-3/2. If you still think its not, please kindly tell me where it went wrong ☺️ @Samiul Haque Chowdhury
I am a business background student. In my university curriculum one of the courses I have found the differentiation. I had no idea what differentiation was! I have done 2 classes and understood nothing. but I find out this video. now it makes sense to me. Thank you Starfish Maths. You are a lifesaver.
Excellent I'm so glad you found it helpful
Same satuation
I'd love to have a math teacher like u..
Bro this 11 minutes long video explains better than what my professor teaches in an entire week lmao, thank you!
I was so confused what differentiation is and how to solve it. These simple questions with different challenges helped me understand to solve. It is really easy and now I love it.
you did what my entire ministry of education's maths website couldn't do, thank you miss starfish i owe you my life
I have a test in 2 days.I am hoping that I'll do well and it's all because of you.Thank you soo much ❤️
How was it? 👉👈
@@adeidra_ It was good
I was really happy with my results 😊
@@adeidra_ umm.. 👉👈
Oh
@@adeidra_ was man tryna pull in a fucking A level maths comments section
This was a very helpful video in helping me understand the basics of differentiation, thank you so much for making this! On a smaller note, there seems to be a mistake in preparing the equation at 5:12.
Thats whats i also😞 think
Me too, I'm confused about that
what us the correct prepping?
Umm but I don't think so 😳... Am i wrong or right?
Exactly ..I was starting to overthink
That kinda hapiness that we get after learning a math lesson and having better confident for the sums is un measurable .... The one who teaches us to that position must be specificaly admired specially in Maths ... Thank you so much Starfish maths for this lovely explanation😊
I was so clueless in class and this really helped me. Took the teacher 2 whole hours to explain in class and i still didn't understand anything. She took 5 mins and i completely understood everything. tysm
wow, this is the explanation so far about differentiation, very simple. I've been on this almost all my life and never quite grasp it. Thank you.
I've never understand differentiation better, thank you soo much for explaining better. This would really go a long way for a beginner like me.
For the last 3 hours, i've been going crazy over the last one on 5:30, i used a diff method to simplify the equation (i used a-b/c = a/c - b/c) and managed to get the one before that correct, and half the last one correct, yet i always got 2x^-3/2 as 2x^5/2 , as i subtracted the power 3 from the power half in the denominator.
same
Omg same😭😭😭
me too dawg
she did mistake. thats the correct answer
I got same too. Keep it up bud
I am studying stage 1 engineering with the OU and recently got onto calculus and differentiation. The books are terrible but watching this made it all so easy!
Thank you 🙏🏼
what university are you at?
focus on calculus 1,2 algebra 1,2
mchanics, applied mechanics, electromagnetism, applied electromagnetism
x The open University for distance learning based in the UK
I hope you have become an engineer @_Whitey_
I literally cannot express myself in words! I can't tell u how much I was struggling with differentiation and integration. But after watching ur videos everything is just crystal clear to me. Thank you so much!
5:26
In the 6th question ( y= 2xcube - 4 ) / √x
When u multiplied....
{2xcube × x to the power (-1/2)}
It will be =
2x to the power {3+(-1/2)}
= 2x to the power {5/2}
🤔🤔But u wrote 2x to the power {-3/2} !
Am I right or wrong?
I thought I was the one who made the mistake. Thanks for clarifying
I've been scratching my head for over 15 mins figuring out that. Then I searched on the web and figured that she's made a mistake. 😊
yes i think she made a mistake there .
She says in the video description that it's a mistake
Indeed you are correct🚬
Love you love you love you. I spent sleepless nights trying to find this and my teacher never made sense so I love you. Thank you so so so much.😂😂😂😂😂
I was same position like you
My teacher can't made sense too
So glad to hear it was helpful! Best wishes
Thank you so much my teacher has been teaching me this for the last 6 lessons and I've had no clue what's been going on until I watched this
Times and Take. This is a good term to remember when differentiating an equation. Thanks a million!
you really just explained in 11 minutes what I've been learning in school for 5 weeks, Thank You so much for this.
3 days of uni explained in 6 minutes. ty
higschool actually
If you spent 3 days on this in uni then you've gone to the wrong place
@@jeansznn5682 not in my highschool.
@@rowandowney553 is it supposed to be less?
What type of school......
It was really helpful to explain what you did in the last three questions. I was able to figure out what to do in question 4 and 5, but 6 was very disappointed that you were not interested in clarifying the answers.
Thanks for a really clear video. Love the written form of the presentation. Gonna watch again and take some notes.
This is the best thing ever that dropped from heaven 😭😭 I could never understand this shit for a whole year!!! I'm glad I found this today luckily 😭❤️❤️
at 5:43 u have done the last equation wrong (helpful but that mistake can misguide some people)
Hi Hasham, you're quite right - good spot. The powers should be added, so 2x^3 times out the bracket with x^-1/2 will give 2x^5/2 rather than 2x^-3/2. Hope that's clear.
Appreciate your reply
and thanks for taking that problem in notice.
omggggg I was so confused!!!!!
I was about saying the same thing....the video was however helpful!
For a moment, I thought my elementary arithmetic was to be questioned. I was right after all. Great job!
THANK YOU, I'VE NEVER UNDERSTOOD THEM FROM LIKE A YEAR, BUT YOU HELPED ME OMG ILY
thank you so much! At first I was really frustrated cause I literally didn't understand anything about it. But after I watched your video, I truly understand differentiation❤️ I'm definitely looking forward to watching your other videos!!
thank you the title is very straight forward and the video too
(new subscriber)
I would kill for your handwriting 🤩
After completing my high school, I understood it now. Thanks for such an easy explanation. Those 2 years got wasted.
Thanks...a million...God bless you to keep on helping others..couldn't miss to subscribe...I love starfishmath..making me a real star..God bless...you more..
I was almost breaking down thinking I could never get differentiation but noooo I found this video and now I'm gonna rock physics!!!
It's been hard for me to understand differentiation because of learning it in 7
But u cleared my doubt.
Thanks!
i'm watching this in 2021 and i'm loving this.thank you so much
Hello ma'am. I would like to ask this.
In the 6th problem (2x^3 - 4) 4x^-1/2.
Why is it that 2x^3 x x^-1/2 = 2x^-3/2?
Is power rule in exponents adds up all the exponents when the variables are the same?
i noticed that as well.. she must have multiplied the exponents instead of adding them.great video tho.
I also didn't get what she got.
I would like to ask if the answer would be 5x^(3/2) + 2x^(-3/2) just I can check if I was right. thankss
It was an error, I got -1/2 for the power for -4x
@@Allen-om8un yeah that's correct.
Absolutely after 2 minutes of watching I loved the differentiation calculas.
Thank you
Great video! I found it super helpful!
Great I understand

Yh very helpful
Hope ADORA passed
i couldnt understand differentiation in class at all as i find this topic not interesting to me, but I had so much homework abt this topic and decided to study and saw ur video. you explained it clearly and in such a simple way. thank you so much for this!
TIMES AND TAKE.....Brilliant! If only we had more teachers like you!!!
lol, this was so easy for further math, thanks for the help, made it 50x easier than my teacher : )
Excellent glad it helped!
Thank you for your videos!!! Its really helping me, I am a part time engineering student.. This really helps me understand maths much better
Thank you Nathan, glad it helped! Best wishes
Mam I from India and I love the way you reach .
Lot's of love from India.
send all love and support to your lovely channel
Your Intro was so beautiful and the Teaching Technique was awesome🌟
Thank you for such a clear explanation. its very easy ti understand and from what i have learnt from your explanation there seems to be a small contradiction on problem 6. I think you might want to have a look at it again . i might be wrong by the way
5/2?
With the help of Starfish maths I can be able to solve any question concerning differentiation without a doubt, Thanks you so much for your time
The last problem at 5:05 has an error. Took me awhile thinking my math was wrong but it was right.
Rewritten:
f(x) = 2x^(5/2)-4x^(-1/2)
The powers for the first part were multiplied in the video instead of adding them. From there I got:
f'(x) = 5x^(3/2) + 2x^(-3/2)
Otherwise good video. Thank you for the review!
That's exactly what I was thinking about. Thanks for it.
It actually feels easy now that you explained them in a nice way. Thank you so muchhh✌️🥺
First I thought It was going to be easy, then after a few minutes, I went "Oh no, I was so wrong", not that difficult compared to my imagination, just absolutely confusing.
Thank you for this, it absolutely helped me
Brilliant, just brilliant,wonderful teaching , thank you very much. You've got yourself a new subscriber
How is 3-(1/2)=(-3/2 )?
It's 5/2
Actually, the derivative for that part is :
5(x^3/2) + 2(x^-3/2)
Plz correct me if I'm wrong 🙂
@Bliss Inc how is possible -3\2 please explain me
@@bullymaguire431thanks!
This exercise is very easy to solve. The third-degree equation has one point. It's really good for the teacher to explain this exercise.
Thank God, this is literally a lifesaver!!! Incredibly helpful stuff, thanks a bunch.
Nomoskar (hello) 🙏 mam. I'm from India 🇮🇳 ( Kolkata) . I love your video. It's great.
Found everything I needed to know about differentiation in this video 🙏 thanks so much
This is the clearest explanation I've ever heard
My whole life was about to end searching for such a perfect explanation thanks!!!!!
Haha you're very welcome, pleased to hear that!
@@StarfishMaths you made a mistake in the sixth one. Shouldn't it be 5/2 rather than -3/2 ?
Really a great and helpful video on differentiation. Finally now I can start integration.
literally saved my grade omgggg
It's amazing video to know how are you doing diffentiation
at 5:48 in that last question don't you think in second step is wrong there should be 5/2 instead of -3/2 you multiplied the powers instead of adding them............
I just graduated in electrical engineering & i remembered i cried over this because i was a VERY beginner & everything was moving so fast (or maybe i was dumb??)
Im so done with this cause in just found this video and this seems easy now? Great video btw 😭
i also got confused with the last equation mistake like how can u be so confident with the wrong calculation, but u can say that was a mistake done willingly to check if we r really focused and attentive :3
Loooool the last one also confused me and I had to battle my mind to remember the laws of indices
Amazing video! Very detailed step by step understanding for me to get it from scratch and for newbies thank you very much, therere many other vids out there that are much longer in length than this video, and do not even explain as well as yours!
super helpful, i learned differentiation weeks ahead of my class and i love it
Thank you so much for teaching Differentiation in the simplest way possible.
Very nicely and easily explained. Thanks ma'am.
Love 💘from India 🇮🇳teacher.....
Fantastic mam love your teaching and the kind of clarity u got is amazing
quite literally got my answer in less than quarter of the vid. thanks!
Thank you for the video. However, there is a mistake in calculating the root of the last equation in the bottom right corner of the table (at the 55:5 minute).
I thought so too. thanks
So true, I thought I wasn't getting it right, but the video was helpful though.
yes I got 5x^3/2 + 2x^-3/2
@@MauxX same, it is the correct answer no worries
@@MauxX how u get it..? Can show the calculation..
Thanks so much, I have my maths exam in two weeks and was completely clueless but just a few of ur videos have helped me way more than my actual math teacher
This was very very helpful, I fell like I’m terrible at maths and I understood easily.Thank you very much!
Excellent glad you found it helpful. And if you followed this you can't be too terrible at maths!
I dont have words to express my gratitude towards this lady🖤
Ok I'm confused on the last problem (of the first 6 you gave). When you distribute the x^(-1/2) across the 2x³-4, wouldn't you add the exponents (-1/2+3) to get 2x^(5/2) for your first term? Or does the adding exponents rule not apply with fractions?
Same Question ⁉️
Guessing she did a mistake
@@mdmahabuburrohmanmeraj8294 She's gaslighting us
Yes there is a mistake as written in the video description.
Noted the same
my high school just flashed fully when i saw this video, amazing explanation.
thanks so much , i was really suffering at differenciation but after watching this video, i was able to solve almost every question i see
I got my note with almost 100 pages and I still didn't knew what is differentiation and how to do it. And you explaned like Khaby lame 🙌🏿 😅 thanks ❤🔥
😂😂
This video is so helpful! Thank you so much, you saved me from a failing grade :')
Glad to hear it!
Thanks so much
This is the first time I understood differentiation
Nice effort , kudos to sarah!
After watching, I really understand now the basic properties of differentiation. Thanks, keep it up.👌
Is 5x^3/2 + 2x^-3/2 the answer for the 6th question
ik i'm 8 months late but yes
