this is a video from
every step calculus dot com
demonstrating how my programs work
on a ti eighty nine titanium calculator
and other calculators in the
t i system
for physics and calculus problems
and let's get started
to access my menu
you have to press second alpha
to put the i n d e x in here
and then you press alpha to put
the eight and the open and closed parenthesis
press enter and you're into my menu
uhm were going to go up
with the cursor to go down to the bottom
you've got u substitution
trig and half angles
uhm quotient rule
but we're going to do quadratic formula
right now
I give you some sort of definition there
of it
write the formula down on your paper
right away
and we're going to enter our variables
you have to press alpha before you enter
anything into my entry lines here
alplha minus seven
ah alpha three
and alpha four
I show you what you've entered
so you can change if you've made a mistake
I say it's ok
and we're going to do the quick answer here
for calculus formula calculator
which this is
here's the variables entered into the formula
that you wrote before on your paper
and here's the answer
exact answer
exact answer
and approximate answer
pretty neat huh
