lim_(x->3) (2 x^2-10)^(1/3) = 2
anonymous
  • anonymous
you arithmetic in wrong but you have the idea right.
anonymous

awww ... ok I thought I was getting it :/
anonymous
  • anonymous
you are but simple arithmetic mistake .

sec ??????????????????????????????
anonymous

what happend to you? :)

nothing...

lim_(x->pi) x sec(x) = -pi
anonymous
  • anonymous
is that clear !
anonymous
  • anonymous
aren't you supposed to plug in pi
anonymous
  • anonymous
pi has an infinite vale so the answare -pi
