Calculus - Find the derivative of a function at a point

[@skyewatson9144]

this just saved my life bc it's too hard to learn calculus in online school

[@demitriuswhite3191]

I swear it is, I’m struggling

[@ahmedalzoyed9525]

Thank you very much, no word can describe what you've done to me.

[@z0n3data]

my calc teacher is genuinely horrible, online school is making this all worse, and the amount of times i've asked questions in zoom class and she replies "you should just know this" is embarrassing so thank you for this. she takes 2 hours to badly explain a concept i can learn in like 15 minutes if it was explained well. seriously. thank you.

[@karldebes]

This is by far the best explanation of a calc concept I've seen.

[@aubreystacy1510]

Thank you! You made sense of a concept for me that no one else was able to. The information about how that equation is derived in the beginning made all the difference.

[@leslieurrutia4548]

Amazing video! I'm going to cry tears of joy because I finally understand, thank you!

[@adamlazaro8288]

Better explaining than my teacher frfr. Thanks for the help

[@NAlamri]

you saved my life, thanks a lot

[@caitygart]

Thank you, this was an excellent video and helped me remember how to solve these types of problems. Greatly appreciated!

[@morganrobinson3066]

Thank you for helping me. I need this. I have a midterm on Friday.

YOU ARE A FINALS ANGEL.

[@beenarajan9982]

Thank you sir you made this concept crystal clear for me.☺😊☺☺☺☺☺☺☺

LIKE YOUR VOICE A LOT...

[@BrickImperial]

great video very very helpful 😍

[@NinaNina-ye2rp]

this video was so helpful! thank you so much

[@alaynadowdall2515]

This is GREAT! Thank you so much!!

[@VJMs]

Great video man!

[@joshhankey8009]

Very good video! What if they give you more than one set of points though? For the problem I have they gave me (3,2) and (-1,0)

[@Camcannon]

+Josh Hankey I think you would just want to then solve for each set and have two seperate answeres because they would be different slopes at different points

[@davitjanashia9344]

great explanation!

[@justjaxie]

Do you have a video showing how to calculate the derivative using the alternative definition? lim x->a (f(x)-f(a))/x-a

[@hlumaxako6086]

damn this helped me so much

[@viplavsinghal2005]

this is amazing

[@lianalisella]

Thank you so much!!!!

[@enayatkapadia1157]

Yes first part of calc 1=done

[@ADISUGEMECHU]

thank you

[@bibhudattamishra1943]

Shouldn't the rise be f (x0)- f (x0+h) as f (x0) is above

[@MySecretMathTutor]

If you want to keep everything positive, then that would work.

[@user-xd9gl4uk3h]

❤️❤️❤️❤️❤️❤️❤️❤️❤️

[@ShivangiSingh-wc3gk]

Shouldn't it be (f(x0 +h) - f(x))/h

[@MySecretMathTutor]

There are a few different formulas you can use for the definition of a derivative. The one you wrote would work if we include the limit as h -> 0.

[@pepsico815]

Doesn't it make more sense to just find the derivative equation, and then plug in 2 for x at the end?

[@pepsico815]

+MySecretMathTutor cool, thanks :)
