Help! (Programming HP 39gs)  Anne  09182008 I'm a high school student right now in a PreCalculus 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 dummyproof step by step walk through. Any help would be greatly appreciated!
Re: Help! (Programming HP 39gs)  Gene Wright  09182008 Go here: You know have two approaches: Approach 1: Use the builtin 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. Approach 2: 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.
