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.
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 UA-cam than in actual class.
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 UA-cam videos and THIS video (for which I'm most grateful) is one of those examples.
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.
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.
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?
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.
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.
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.
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.
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.
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
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..
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?
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
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............
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 😭❤️❤️
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!
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 🙏🏼
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😊
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?
TThe mistake at 5:43 is that you multiplied the exponent of 3 by -1/2 whereas you should have subtracted 1/2 from 3. The correct answer to this question is: y = 5x^3/2 - 2x^-1/2
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 just wanna thank u🙏, no joke my calculus teacher for 3rd yr manufacturing engineering which is mostly theoretical & have a full subject of calculus on my 1st term 1/2 of the academic yr just he puts stuff on the board & doesn’t explain like u do. these vids which clear & simplicity just makes calculus understandable & learnable - tho i still have questions. i never had a teacher who doesn’t explain, can’t believe it , but vids like urs help thx🙏. we now have “semesters” which i swear it’s an american thing, used to be called “terms” it’s my college’s 1st time doing semesters/terms (UK system). at least my further maths teacher does explain.
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!
the video is correct, 1/3x^3 = x^2, because the 1/3 was multiplied by 3 from the "raised to 3" resulting to 1 and the "raised to 3" was minus'd by 1 resulting to to raised to 2
@@radinkalappen551 you're correct about the first thing you said in the original comment "1/3 was multiplied by 3 resulting to 1", but you were asking how did the 1/3x^3 resulted to x^2 right? the video just get the differentiation of 1/3x^3 using the power rule = n*ax^n-1 iirc resulting to x^2
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 so much you actually helped me out, i had no idea what differentiation actually meant, but your video helped me out so much. thank you may gob bless miss.
Hey at 5:18 x power 3*x power -1/2 means a power m into a power n means a power m+n so x power 3-1/2 means 6-1/2 so it's 5/2 .. if i am wrong plz do correct me if not correct yourselves mam 😊
5.28 there is a mistake. the answer would be: 5x^3/2 + 2x^-3/2

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 🙂

You have to deduct -1 from the powers.

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

10:57 could any one explain how did we get 2a after the second differentiation
coefficient of x is 1, multiply 2a with 1 (remains 2a) and subtract 1 from the coefficient of x. Since x^0=1 you get 2a.
TThe mistake at 5:43 is that you multiplied the exponent of 3 by -1/2 whereas you should have subtracted 1/2 from 3.
