this is a video from every step calculus
dot com
demonstrating how my programs work
on a t i eighty nine titanium calculator
and other calculators in the t i system
for physics and calculus problems
I'm going to show you how my programs
tackle quadratic formula problems
and let's get started
you have to press second alpha
to put i n d e x in here
you have to press alpha to put
the eight and the open closed
parenthesis
press enter and you are into my menu
ahh it's all alphebetical this menu
and all of these choices will help
you pass calculus
I'm going to go up with the cursor
to get down to the bottom
to get to the q section
and here's the quadratic formula
and we're going to do some
quadratic formula problems here
uhm I always give you a definition
of a problem if I can to help you
a little bit about your knowledge
of the problem
you write this formula down on
your paper right away
and then we enter the variables
you have to press alpha to enter
anything into the entry lines of
my program entry lines
I'm going to enter alpha
minus nine for a
going to alpha eight point three for b
going to go alpha seven
I always show you what you've entered
so you can change it in case you've
made a mistake
I say it's ok
I'm going to do the step by step
version on this one
and show you how it does everything
it adds the variables here
and then it would just like you'd have to
do the calculations
as you go each screen
you mark down the calculations
just as you see them
and here's the exact answer
and here's the approximate
exact and approximate
of that answer
pretty neat huh
