This semester I am a teaching assistant for Calculus. There are many students from different departments like International Relations, Economics and more taking the course. The course is comprehensive. For example, we gave the "epsilon-delta" definition of limit, we find the derivative of functions using the definition of derivative, find the equation of tangent line that passes through a point on some function. I am trying my best to explain what are we doing during class; I draw graphs to explain formal stuff, give daily life examples while finding a delta for a given epsilon. However, I can see the pain in their face and that bothers me a lot because I want them to understand or at least pass the class with a relatively high grade.

So, can you give me some examples related to your department that I can use in Calculus, or some advice about to increase the level of understanding of the course? Any answers will be appreciated, thank you.

    Ask this in the Mathematics Educators StackExchange. – Dave L Renfro Mar 15 '17 at 16:03
  • "give daily life examples while finding a delta for a given epsilon" I am puzzled, but intrigued, by that. How does finding a delta for a given epsilon relate to (non-mathematical) daily life? – Pete L. Clark Mar 15 '17 at 18:50
  • In short, my example was: I am cooking and in order to make my meal taste "the best" I have to add 8 gram of salt. So I said that close to the best I feel if I add an amount of salt between (7.9,8.1) or something between 7.5 and 8.5. As we do in taking a limit, we exclude the point 8 from the intervals, so, that was my explanation. – Ninja Mar 15 '17 at 19:33

    Um, why are you trying to reinvent the wheel? There is no shortage of calculus textbooks that contain examples and problems that are labeled as being relevant for this target audience. – aparente001 Mar 16 '17 at 10:31
