This is a video demonstrating how my downloadable programs work in your TI 89 Titanium Calculator and other t i calculators for Calculus and physics problems. Let’s get started here you have a second alpha to you press second alpha to put the i n d e x letters in here the press alpha to put the eight and open and closed parenthesis and you press enter and you’re into my menu. I’m already at integration by parts but you can scroll up to whatever you want you notice the number of choices that go way above the screen
and way below for you to pass your calculus maybe do your homework we’re going to go integration by parts and you want to go cosine and you have to push alpha to put any thing in the entry lines here press that remember to do that and we’re going to put the function in here x squared times the cosine of three times x I always show you what you’ve entered so you can change it if you want say it’s ok and you start you find first the d v and that’s the most difficult thing to integrate so we put that here ahh and then you’re finding v which is the integral of cosine of three x ect. you write all of this down exactly as you see it on your paper and then we do the formula here’s the formula and we add the ahh they require here’s the v which is here and u which is here x squared and here’s v again and then the derivative du which is two x and you just keep marking things down takes two integrations and so we do it again keep writing all of this down on your paper and here’s the answer here you combine all of it right here. Pretty neat, huh? everystepcalculus.com. Go to my site buy my programs and pass calculus.
