<p>I know how to do them but am trying to go back and review them on a more theoretical level. I know the informal definition of limits but I just cant seem to grasp the epsilon delta definition of a limit!</p>
<p>no youre not stupid. intuitive definition of limit is cake, epsilon delta definition is harder and its not on the AB or BC exams. some higher calc classes teach it, but in lots of AP classes you wont even see it.</p>
<p>It's not that I'm afraid of it being on the exam. I was just afraid that this was standard HS AP material and that I was stupid. (Sigh of relief). :)</p>
<p>no... nothing to be ashamed of, infact, i have no clue what you're talking about!</p>
<p>I never learned the formal definition.</p>
<p>But, confound it, when I study Calculus II I will learn this by myself...</p>
<p>We learn the formal definition after the AP test (AB class). I haven't read it myself yet so I don't know what it is either as well.</p>
<p>the definiton itself is not very hard to understand.. using it for proofs is hard...</p>
<p>it's really easy its probably the book you're using doesn'texplain it well</p>
<p>I tried to learn the formal definition at the beggining of Calc. Was hard stuff, and I thought it was suppose to be easy.</p>
<p>In my dad's indian textbooks for Calc 1 and 2, epilson-delta is the first thing they cover...</p>
<p>"I just cant seem to grasp the epsilon delta definition of a limit!"</p>
<p>Just look at epsilon and delta as distances; when one gets smaller the other will get smaller.</p>
<p>it was the first thing we learned....its actually just your intuitive definition put into math words....that simple (but not understanding it at first does NOT make you stupid in any way)</p>
<p>i remember i was absent when the teacher gave the lecture on it...but i read the explanation in the textbook we're using and it was very simple...at first when you look at it it's like wt heck is this...but try to reason it in simpler words and like someone said, distances. I'm sure there's many websites that would have it explained well..try dr.math i think it is..google it!</p>
<p>Delta Epsilon proofs only account for one multiple choice question on the BC test, and arent even seen on the AB test.
So yea, dont bother really learning it for the BC exam.</p>
