Calculus ProblemI have a problem related to derivatives....Please email me the solution, if possible #2 20060224 01:08:02
Re: Calculus ProblemThe fallacy is that you are differentiating wrt x, but your function is not definded until x itself is defined, but then x will be a constant. Moreover: in d/dX (X+X+X……..Xtimes) the "function" in the brackets is NOT defined at the time of differentiation and so cannot be differentiated. #3 20060224 07:53:05
Re: Calculus ProblemThat is correct. "(X+X+X……..Xtimes)" is a function! If you are going to evaluate it first, then you have to evaluate the other side too. "The physicists defer only to mathematicians, and the mathematicians defer only to God ..."  Leon M. Lederman
