Simpsons Rule on the TI-89: Raw Transcript
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
