This is a video from EveryStepCalculus.com demonstrating how my programs work on a TI-89 Titanium calculator and other calculators in the TI system for physics and calculus problems
okay partial fractions. Uh, to get started on my programs you have to press 2nd Alpha to put in i_n_d_e_x in here then press. Alpha to put the 9 in open and close parentheses press enter and your into my menu. I’m already at partial fractions you see there’s a menu here, all alphabetical that
you can scroll down to up to we want partial fractions right now you have to press Alpha before you put in anything into these entry lines here remember to press Alpha and put in the function 1 divided by the quantity x squared plus 2 times x, I’ve already showed you what you’ve entered so you can change it if you want. I say it’s okay first of all we factor the denominator it’s already factored here and we choose our A&B and b would be x and x plus 2, equals 1 and then we multiply by the common denominator which I showed you in the previews one you get x, or a times x plus 2 plus b times x trying to eliminate one parameters one variable a in this case so we multiply by a -2 or I mean add by a -2 we’ll get a zero so we choose that one and then we figure out what b is, and then we can use that to figure out what a is and here’s a and your three halves, here’s your partial thing for your answer for your calculus test pretty neat huh?
