I have tried approaching teachers, reference books, friends who are at a much higher level of maths.

What is a way to approach these proving questions for calculus.

Despite knowing how to do derivatives from Class 11 ALL of my providing questions despite all efforts are going wrong.

I don't know how to bring it to that final proof.

Don't get me wrong I can do derivatives. Just this is really fuking me up

These .io sites are scam sites are something this subreddit has been saying. Im trying to download a few textbooks but i realised it making me pay for fast downloads in both the slow and fast ones and the problem is i logged in because i though annas-archive is doing that now to deter bots and scrapers.

Is there something i can do to fix this??
