Im having trouble starting the harder optimization problems in stewarts calculus (calculus 1). I noticed one of my major problems is not knowing how the picture of the optimized problem looks like. My test is only going to contain one optimization problem. So I am not worried about failing. My problem is I want to understand. Will returning to geometry after the semester ends help me get better at these types of problem? I have kisselev planametry and sterometry on hand but I think it is too late to start looking at them now during the semester. I had a similar problem with related rates. I understand everything else tho.
