### Integration by Parts on the TI-89: Raw Transcript

This is a video from EveryStepCalculus.com

demonstrating how my programs work on a TI-89 Titanium calculator and

other calculators in the TI-89 systems for calculus and physics problems

okay

integration by parts

with regard to cosine, anytime you’re trying to integrate something and it

becomes cosine or sin

or natural log

e to the x your into integration by parts

so remember that let’s get started

You have to press second alpha to put the letters i_n_d_e_x in here then you have to

press alpha to put the 8 in and open and closed parenthesis to press enter and your

into

my

menu It’s all alphabetical were going to scroll down here to integration by parts

you want to do cosine, so we’re gonna

scroll down to.. we could press the number four here and let’s do that because the

number four and it automatically goes to cosine

integration by parts

And we’re into the program, you have to press alpha before you

put anything into these entry lines here in my programs, we’re going to press

Alpha

and put the function in here, we’re going to put uh…

the alpha 2 times

x

times

2nd cosine

of 3 times x

goes off the parentheses press enter

I always show you what you’ve entered so in case you made a mistake you can change

it

I say it’s okay I’m going to press number one here

And you notice a dv is uh… the

function that we’re going to integrate

and i show you how to do that

You just write all this down on your paper exactly like to see it

don’t even think about it

and u is 2x and du

is 2

dx

and here’s the formula here v times u minus the integral of v times d

u dx

and you place that all in here, that’s what we’re doing here

pressing the enter button to go to the next screen, write that down you can look at it

and study it.. it’s all accurate

and here’s the answer

2x sin 3x divided by 3 plus one ninth cosine of three

x plus c

pretty neat huh Every Step Calculus dot com got on my site
