I've recently begun Calculus 1 and if I'm honest, so far it's been challenging aswell as fun. The biggest problem for me so far has been understanding the content. Instead of attempting dozens of questions with intent on drilling methods into my head, I've been reading many different books and watching many different videos. However, I can still tell I don't understand the content fully. For example, I still can't construct Epsilon Delta proofs confidently and there are a few proofs I still don't understand.
I started Calculus three days ago and have spent about 18 hours in total. The topics I have covered so far is:
Derivative as Rate of Change, Limits and Continuity, Discontinuity, Calculating Derivatives, Derivatives of Sine and Cosine, Limits of Sine and Cosine, Product Rule, Quotient Rule, Chain Rule and Higher Derivatives
I would like to ask how can I acquire a deeper understanding of the topics I've learnt?
Also, should I continue watching videos in an attempt to fully understand the material or should I start attempting to solve problems?
