this is a video from
every step calculus dot com
demonstrating how my programs
work on a T I eight nine
Titanium Calculator
and other calculators in the
t i system
for physics and calculus problems
I'm going to show how my programs
do a quadratic formula proof
and let's get started
you have to press second
alpha to put the i n d e x
in here
you press alpha to put the
eight and the open and closed
parenthesis
press enter and you're into
my menu
you have many choices here
so you can pass calculus
and do your homework
we're going to scroll down
to the q section here
and
see if we can't find
quadratic formula
do the calculations on
a quadratic formula proof
I give you always a little
definition of it so you
know what you're talking about
with the quadratic formula
and why
you write this formula down
on your paper or homework
right away
and you enter your variables
you have to press alpha
before you enter anything into
my entry lines of my programs
remember that
so we're going to do alpha
minus six
alpha minus five
and alpha nine
I always show you what you've
entered in case you made a
mistake
and we're going to do the
quick answer here
well on the proof will do
the full answer
ah you enter the variables
and write this on your paper
here they're entered into
the formula
and then you do the calculations
just like you would if you were
doing the
calculations yourself
write everything down you see
go through each screen
and you got the exact answer
here the approximate answer
exact answer and
approximate answer
for x
pretty neat huh
