my God!!!!! So parabola is so easy this way, after other videos ended up confusion my life the more. Bro you are the best. And may God continue to bless you.
I would recommend trying a procedure quite like this one but instead of assuming the point is at the origin try placing the point there at some arbitrary place and setting up equations like the ones here. If you do a similar process as the visor above you will likely be able to obtain an equation that you can substitute b and c into like he did with 1/4p = a
I know this is an Algebra II video but could you please prove that The integral from a to b of f(x) is equal to the antiderivative of f(x) at b - the antiderivative of f(x) at a ? (Fundamental Theorem of Calculus) Right now I am starting Calculus III but I still wanted to know why the derivative and integral are inverses? F(x) + C = S f(x) dx Thanks
+Lucas M they are fundamental theorem isn't it ? can fundamental theorem be proved? i still wonder? Can we prove why arcsin theta and theta are inverse to each other? this may be due to definition aye?
+Lucas M Yes, arcsin(x) is the PARTIAL inverse of sin(x) because you should notice that sin(x) is not a one to one function. So mathematicians restricted the domain of arcsin(x) to -1 to 1 Yeah, it is simply by definition. arcsin(x) = theta and sin(theta) = x
Lucas M Yes you are correct . I think we need to see www.khanacademy.org/math/integral-calculus/indefinite-definite-integrals/fundamental-theorem-of-calculus/v/fundamental-theorem-of-calculus for fundamental thoerem of calculus :)
rcfoley The video derives the general equation of a parabola, y=ax² where a is a number. Since p is a number, 1/(4p) is also a number and thus, can be substituted with a.
We just let 1/4p = a We are the ones that choose it. You can choose any letter you want to. The purpose is just to simplify the equation of the parabola.
Unfortunately, this lost me at 1m 50 seconds:- ie the expression "root d1-d2 etc etc" - it would have been better if this expression had been dissected and explained further.
Hello! I'm Brazilian! And i am new on the channel but i don't understand english pronunciation very well please subtitle the vídeo in english because would help me a lot... i love your videos :) They're very interactives. #mathematic is more easy with you!
you really deserve more credit, this video helped more than 2 hours with my teacher, thank you so much
my God!!!!! So parabola is so easy this way, after other videos ended up confusion my life the more. Bro you are the best. And may God continue to bless you.
Perfect, beautiful, top notch, down to the point, crystal clear anglo-saxon didactics (as opposed to french didactics 😣😣). It's a relief.
I was finally able to understand the process that was pictured in my textbook! Thank you so much!
You are best bro. Thank you so much for videos. Please share video often .
This is the easiest explaination I've ever seen............... This video went into the core of my brain...... Thanks a lot buddy
why did this channel die? it was great
yeah man...
Thanks for another great video!
Would you make one about the distance formula please?
hello mathematics online can you be active regularly :( i really miss you alot .
Very good explanations really amazing...... Very clear
superb description...really liked it
Please come back with your quality content.
Do you mean that his videos were better before!?
Thanks mathematics online your vids really helped I was confused with this thanks
how do we know that every parabola has the equal length to the focus and directrix point though?
Wow ....
And which software or app was used to draw figures? ( geometry was awesome 👏🏻)
Great animation
Well done! ❤
Why does a parabola concentrate in coming rays at the focus ?
How do you make your videos? With witch program?
Funny how most people are not asking math related questions but instead they are asking the software being used😂😂😂
I need some more proof; like y^2=-4ax and the rest of the equation of parabola...Thanks and great work!
Can you prove and find the area of three dimension elipse?
What mathematical software do you use for your dynamic algebra?
How do we REALLY know that the distance D1 is equal to D2? Or is that just the definition of a parabola?
aeroO bics just the definition
how about y = a(x - h)² + k ?
Love it.
How if there are constants such as c or even Bx is involved?
I would recommend trying a procedure quite like this one but instead of assuming the point is at the origin try placing the point there at some arbitrary place and setting up equations like the ones here. If you do a similar process as the visor above you will likely be able to obtain an equation that you can substitute b and c into like he did with 1/4p = a
What is the procedure to contact you?
+I Love Engineering hello
+mathematicsonline Actually I want to know can I post your video on facebook with giving you, your youtube channel reference credit?
What kind of software did u use? Plz tell me.it is very very good explanation
#prsclasses
the formula for parabola given in my textbook is y^2= 4ax, u wrote y = ax^2, shouldn't it be a^2?
Thank you bro
How d1 is equal to d2?
cool intro
I know this is an Algebra II video but could you please prove that
The integral from a to b of f(x) is equal to the antiderivative of f(x) at b - the antiderivative of f(x) at a ?
(Fundamental Theorem of Calculus)
Right now I am starting Calculus III but I still wanted to know why the derivative and integral are inverses?
F(x) + C = S f(x) dx
Thanks
+Lucas M they are fundamental theorem isn't it ? can fundamental theorem be proved? i still wonder? Can we prove why arcsin theta and theta are inverse to each other? this may be due to definition aye?
+Shirshak Bajgain
I don't quite understand you statements.
I think you mean, why is arcsinx is the inverse of sinx
+Lucas M
Yes, arcsin(x) is the PARTIAL inverse of sin(x) because you should notice that sin(x) is not a one to one function.
So mathematicians restricted the domain of arcsin(x) to -1 to 1
Yeah, it is simply by definition.
arcsin(x) = theta and sin(theta) = x
+Lucas M
You should graph both functions by hand. It may help you.
Lucas M Yes you are correct . I think we need to see www.khanacademy.org/math/integral-calculus/indefinite-definite-integrals/fundamental-theorem-of-calculus/v/fundamental-theorem-of-calculus for fundamental thoerem of calculus :)
Go for the hiperbole equation!!! please
yes!
Thank you
how did we discover about parabola? and other conic sections
Can you plz make a video on volume of cone
why cant you prove it without knowing any coords or lines?
Please make on parabola equation derivation
Where did a come from and why is it equal to 1/4p?
rcfoley The video derives the general equation of a parabola, y=ax² where a is a number. Since p is a number, 1/(4p) is also a number and thus, can be substituted with a.
The value of "a" was arbitrarily chosen to simplify the equation as much as possible.
We just let 1/4p = a
We are the ones that choose it. You can choose any letter you want to. The purpose is just to simplify the equation of the parabola.
Come back :((((((
Great!
can some one help me know on how to derive the standard equation of x^2=4py
this is genius
Come back :)
YES
1:30
come back
What happened to you bro?!😑😑😑 Where are you?😓 Please come back!
He is now.
Unfortunately, this lost me at 1m 50 seconds:- ie the expression "root d1-d2 etc etc" - it would have been better if this expression had been dissected and explained further.
That's just the distance formula.

🤯🤯🤯
Sir plzz hyperbola ka video me update kigiye
Uuuhhhuhhuhuh Awesome
VAMOS
😉
f(x)=x²
this reminds me of why i hate math. regardless, good video.
Could you accept the subtitle please?
thanks for your support!
Thank YOU for the content !
huh..
Thank you
Thank you
