I think I am going to use both methods so I am sure that I am correct, it will take a while, but at least I will know how to answer this type of question in the future! I will be sure to remember what a energy argument is!
thanks again!
Hi, I am new here, and am not expecting any direct answers (I read the sticky) but I am pretty confused about this one question:
