A Proof of the Chain Rule

[@Lu_Orellana13]

I didn’t understand and was going insane until I found your video. You cleared up all my doubts! Thank you so much!

[@saichintagunta7553]

small thing I think that it is supposed to be rho(y)[y-f(c)]. It is written as rho(y)[y-c] in the video. I found the video really helpful thanks!

[@dosomestuff1949]

thanks man, that confused me

[@tatertot4810]

Thank goodness for writing this. I was like “wtf is going on here??” Lol

[@AlbertoGirardi747]

Thanks, I really struggled to understand where that statement came from, I suspect this and I'm glad I found comments supporting

[@kaikai8869]

Where did you find the proof or you invented yourself?

[@cooking60210]

It's in a lot of books. Most real analysis books will give this proof.
