this is a video on my programs and how they are applied to the ti 89 titanium
calculator programs for that calculator
today I'm doing a video on limits in particular
when a limit is undefined and let's get started
in my main menu you have to get to it by pressing second alpha
and press the letters i n d e x then press alpha again put the eight and open
and closed parenthesis and then press enter and you're into my menu
there's many things as you can see in this menu, goes all the way down
scrolls all the way up or down parametric equations
log of x many many things for you to pass calculus
and do your homework right now we're going to do limits
and we scroll to that we have several options under limits
table of limits is when they have you on a test
put a table down on each side of the approaching point
to get the limit I do that too for you to here, but right now
were just going to compute a limit and we have to press alpha befoe we enter
any function in my entry lines here in my programs
but let's put the function in for the numerator
x cubed minus seven close off the parenthesis
divide it by the denominator alway use plenty of parenthesis
x squared minus four as x approaches two
alpha two I show you what you've entered
you can change it if you've made a mistake but this is x cubed minus seven for the numerator
x squared minus four as x approaches two right away I compute the denominator
and it turns out to be zero so that makes the function undefined
and now our job is to find the limit of that point
where it's undefined so increase the point by one hundredth
and put it into your function you put this stuff exactly like you said
like it is here on your paper or homework and you're just substituting that number
two point zero one for x in every value of the function
and I show you what that computes out to do and you can get an a on this problem
the limit is twenty seven point nine pretty neat huh?
