TI-M: Limits
I was wondering if someone could shed some light on limits for me? I
want to know 2 things how to do it by yourself and then how to do it on
the 89. So how would you figure a limit out in your head, for example,
find the limit of f(x)= (x-1)/(x^3-2) when x approaches x. How do you
know that it is 1/3? I get that on the 89, but i want to know how to do
it without becuase i don't want to get lost in calculus and we are just
begining limits. Now how would i get an answer on my calculator, like
this. lim (x+1)/(x^3-1) x is approaching 1+(but the positive is a
superscript)? when i put in my calculator like this
lim((x-1)/(x^3-1),x,1,positive) i get undef but the answer is supposed to
be +infinity. What am I doing wrong?
