Almost 11 years and you’re still helping students out 💯
how did he get 64 again? My calculator does not have that
thank you very much
I love you 💕❤️
dx means what?
why is this 5 minute video more informative than my two hour calc class?
just a question though, where did you get f(x) = x^2 ?
Someone say SIGMA?
ty. the integral videos are superb and I'm having an easier time with this than limits themselves. is this usually the case for most people?
Im wearing earbuds right now and it's so uncomfortable how I can hear every splosh of your saliva and every sniff of your nose. It is so distracting.
You lost me at 3:43, where did that power rule come from?
this lecture contain super logy and concept
why dont we put c constant of integration
tried the equation on desmos it worked 🙂
its cool that when you have f1(x)=ax/|x| and you have variable A for an equation, the y axes will be flipped where y : 1 => y : -1 and y : -1 => y : 1 IF the point is below x : 0
I love you
Wait what about the plus c's? Is it acceptable to discard them and not even write them out in this situation?
My video about definite Integrals is exactly like this but with real paper
The sign for Integration comes from the LATIN LONG 'S' which essentially is short for Summa which in turn is short for SUMMATION which is what Integral Calculus is all about.
Leibnitz was the first person to use that symbol!!
The letters dx stand for INFINITESIMALLY SMALL particles of the variable x in this case
Hope this helps.
Here to study for a calc final tomorrow, anyone else?
Within 5 minutes, it became so clear! Thanks!
3:45 but is it not 2x instead of 3x^2? Also at the end he mentioned square units but exactly what square units?
Slowing it down to .5 makes him sound drunk. lmao
Made me learn it for about minutes….. OMG Commended Khan Academy!
I'm sorry, but am I the only one hearing a mosquito buzzing in the background (I have headphones on) I couldn't concentrate!!
Everyone watch at 1.25x the speed. It is much faster and equally understandable. Good luck and God bless 😀
I freaking love you
I've just got to say that you all are the biggest help in the whole world, thanks so much!
that just alleviated my fear of definite integrals. I thought I had to evaluate it and get the sum of all values between the two numbers.
When do you plug in functions then? Isn't that definite integration?
Khan: 0:1 *&^%^&*&^^%^&*(*&^% 5:37
me: ammmm !!!????
khan : 5:38 sixty three over three, and three goes into sixty three exactly 21
me : finally some thing i know
