Hey
i was wondering how do you find the stationary point after you differentiate via the quotient rule. i know this question is general- see how some differentiation by the quotient rule are complex, how would i find the stationary point.

Hmm. for example..

y= √x²+1/(x-9)²

how would i get the stationary point for something like that.
Thanks in advance.

Im pretty sure that first u would find the differentiation using the quotient rule and than make the differentiation of it = 0, from there u can find wat x is by working out the equation ur left with. From there u can work out the nature of the point if needs be (such as if the points a minumum or a maximum) and u can draw the graph 2. Now, i havent done a question exactly like that before (i mean involving the quotient rule) but ill be glad if anyone who's certain of the answer can correct me if im wrong. :rolleyes:
