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 ok

simpson's rule ahh an approximation on a definite integral

and let's get started puse second alpha to put the letters

i n d e x in here press alpha and put the nine and the

open and closed parenthesis press enter and you're into my menu

many choices here for you to pass your calculus two class

we're gonna do simpsons rule and we're gonna do what's up here

in the example this is on the you tube by one person

professor or who ever and so we're gonna enter that

you have to press alpha before you enter anything into my entry

lines of my programs so I'm gonna press alpha and put the

one divided by course always parenthesis

x to the fifth plus one close off the parenthesis

press enter I always show you what you've entered

so you can change it case you made a mistake

and we're gonna put in our range alpha two to alpha seven

again I show you I say it's ok

here's the simpson rule formula right out of the calculus book

doesn't tell you much took me two days to figure the real formula

out which is this

and uhm you write this on your paper

I don't think it'll appear on a test too difficult but

ahh probably for homework were gonna do six intervals

and change of x is b minus a, that's the upper limit

minus the lower divided by the number of intervals

and that equals point eight three three and we start our calculations

according to the formula and you write this all on your paper

I'm gonna do it quickly here notice this is changing

substituting in for x to the five plus one each time

and then you sum up all the calculations if you write this on your paper

your gonna look like a genius one point one two square units

which is the are of that uhm definite integral

pretty neat huh every step calculus dot com

go to my site buy my programs

and pass calculus
