In class - diffrenciate (5x⁴+1)²😄🥰(In my mind - i think i am getting better in maths😏😏) In exam - if xloge(logex) - x²+y² = 4 (y>0) then dy/dx at x=e is equal to ??(wtf.....)🤯🤬🤧
It's -72 units/sec first you have to differentiate equation of curve with respect to x , Then you can simply get the slope and after that you can differentiate that eqn of slope with respect to time because we have to find how fast slope of the curve is changing. 😅 I hape it's right!
y=(5x^4+1)^2 (Given) Granted, you can use the Chain Rule, here, but since the exponent on the (5x^4+1) is just 2, frankly, I'd just multiply it out, first, before taking the derivative. (5x^4+1)^2 =(5x^4)^2+2*(5x^4)*(1)+(1)^2 =25x^8+10x^4+1 y=25x^8+10x^4+1 (Re-written) Now we can just take the derivative term-by-term (The first two terms can be differentiated by using the Power Rule, since we have variables raised to real-numbered powers, and then the last term is a constant, so its derivative is just zero (0)). (dy/dx)=25*(8x^7)+10*(4x^3)+0 =200x^7+40x^3 GG.
@@digaddog6099 look yes +C is 0 so it wouldn’t change anything to integrals it could be the same with a derivative but some rule is where +C is only used for integrals but not derivatives

Thanks I applied the chain rule to my literature essay and got full marks 🎉
how

I had a homework question the other day that was differentiate 2log(3xsin^2(5x^2-9x))
double chain + product took me out
For the given curve: y = 5x - 2x3, when x increases at the rate of 2 units/sec, then how fast is the slope of curve changes when x = 3?
Solve please 😢

In case you don't know I have done dy/dx it's just to obtain slope (m)
@@jeremytowns9922yeah thats some normal calculus shi🤣not for the weak im strugglin myself
Bro your scaring me I'm only in 7th grade
This is 9th grade stuff bud
@@Joegattofan27 You don’t learn calculus in 9th grade.. what country are you from??
@@Joegattofan27 10, but ok. Its an optional advanced type of math in 9th grade
Me in 1st grade: 👁👄👁
This is 11th grade stuff
Bro what?
School hacks? Just use the chain rule? Now find the length of a hyperbolic function using that
You can't even do that 😂
My god!!! Such a life saver this is😭😭😭😭👌🏼
This is the most basic derivative. Looks like nothing you’ll be tested on.
Obv, this is only to introduce it.
Dawg next year imma get this shit?
Video on integration by substitution 11th grade
Sir plz make more videos on chain rules and other equation
Thank you you saved me
this an easy derivative where the rational functions with radicals lol
was that a deer in the background?
How is this a hack it’s literally the first thing they teach you after elementary derivatives
We all do that bro😐 it's already been happened everytime in my class lol
Generalised Power Function Rule?
👍👍
Bro chose the easiest example
Now integrate to solve for y🐢
💀💀
I never learn this in 🏫 neither of my teachers never taught me this in my life. I want to learn I want my GED 🎓 I want to experience college

(5x^4+1)^2
=(5x^4)^2+2*(5x^4)*(1)+(1)^2
=25x^8+10x^4+1
y=25x^8+10x^4+1 (Re-written)
Now we can just take the derivative term-by-term (The first two terms can be differentiated by using the Power Rule, since we have variables raised to real-numbered powers, and then the last term is a constant, so its derivative is just zero (0)).
(dy/dx)=25*(8x^7)+10*(4x^3)+0
=200x^7+40x^3
GG.
Now I’m in 7th grade. Though I doubt it will take me long to understand because I’m doing trig ratios in year 7
😂😂. Make more videos soon. But fuck calculus ... do Calculus 2 . I remember the chain rule.
Can we solve it by expanding?
Yes, definitely but this is just faster and also results in the answer being in factored form vs standard form
I did it by expanding and got a different answer

10x•cot(5x²)
That ones also pretty easy
Too fast talking to fast

Atleast you can use this in 12th if you can remember it

can i ask why y turns into dy/dx?
