|Help! (Programming HP 39gs)|
Message #1 Posted by Anne on 18 Sept 2008, 2:48 p.m.
I'm a high school student right now in a Pre-Calculus course. We have to program the Quadratic formula into our calculators. My problem is that the curriculum is based on the Texas Instruments.
I have checked the manual, the HP website, and numerous friends. And am still having trouble.
I don't know how to input the raw commands into the calculator to form the program.
I need a dummy-proof step by step walk through.
Any help would be greatly appreciated!

39gs learning modules
You know have two approaches:
Approach 1: Use the built-in aplet on the 39gs called the quadratic explorer. It is shown in the PDF file for the working with aplets learning module. I highly recommend going this approach.
Download the PDF file for the solving equations learning module.
Read through the module once downloaded.
Then go back and instead of entering the example shown on page 2 of the module (the example shown is v^2 = u^2 - 2ad), key in your quadratic equation. If the quadratic equation you're needing to solve is x^2 + 5x - 6 = 0, then key in the equation and leave out the "= 0" portion.
Continue through the example in the learning module using the quadratic equation you entered.
Should be good to go.
