Antiderivative Calculator Video TI-89 Key Points
How the antiderivative calculator (TI89) solves the definite integral:
~ Bring up the menu and scroll to definite integral
~ Enter functions by pressing alpha before
~ Enter your range
~ Program will review and ask for changes
~ It will substitute the lower limit of your function
~ It substitutes upper from lower and produces answer all step by step

This is an antiderivative calculator program or app for a definite integral to get to my main menu you press second alpha to enter the letters i_n_d_e_x and then press alpha again to enter the eight and open and close parentheses and press enter in your into my menu you scroll down to where your choice is but in the video I’m demonstrating a definite antiderivative definite integral so we’re going to scroll down to you can see the difference choices here in the A & B vectors here acceleration chain rule concavity that’s graphing by hand cosign of a to the x integrated i’ve done that and other video uh… integration by parts and so we’re going to school down to cross product definite integral press enter and were into the program for this problem were going to enter our function so we can enter whatever we want here but let’s do the example here you have to press alpha before your can do anything and my entry lines here x squared plus x minus two we have to enter our range as our function here when the rangr alpha two alpha seven and show you what you’ve entered here change it if you know i say it’s ok and here’s the integral of of your function and with regard to the um… parameters for range and substitute the lower limit thats in your function turns out to be a hundred and twenty five and you process the lower limit six sixty seven take the upper from the lower and here’s your answer and divide seven forty five or six to get the approximate answer this is the exact pretty neat huh? EveryStepCalculus.com you write everything down on your paper and my programs here to get everything uh…correct using the the antiderivative calculator program or app enjoy my programs and uh… pass calculus
