Hi. Right now I'm working on Morris Kline's Calculus: An Intuitive and Physical Approach after having finished Saxon's Advanced Mathematics (precaclulus book). I came in feeling strong and now honestly I just feel very frustrated. I can do something like 60-70% of the problems but there seems to always be a few problems that I have just no idea what to do. Differentaition (product rule, chain rule, quotient rule) i have down pretty well but mainly because that all just seems like an simple extension of algebra. I'm mainly struggling with the word problems/applications, which is unfortuante because the whole point of this book seems to be get the student to do applications. Some word problems I don't even understand what the question is asking me! So I'm wondering. If I can get through 60-70% percent of the problems, should I really stick it out on the tough problems or should I just skip them? The book is called an intuitive approach but honestly it seems quite unintuitive at times. The thing is my goal is to complete the following books after this one. How to Prove it - Velleman Calculus Vol 1- Apostol Linear Algebra and Its Applications - Strang Calculus Vol 2 - Apostol Concrete Mathematics - Knuth Since i have plans of going over Apostol's calc anyway, I wonder if it's okay to kinda skip through Kline's book and only get the major ideas, doing the simpler problems only. Question: Is there a limit on how many questions I can ask a day? I'm studying math ~8hrs a day (for better or worse). For some reason I'm a little nervous to ask questions. Also this book is a physical approach. A lot of the questions are Caclulus mixed with Physics. What would be the appropriate homework section to ask for help?
