Help entering formulas on calculator

[Kryptonite]

I have both a HP-50g and a TI-89T so let's not get into the debate of which is better...

I am basically trying to find the most efficient way to enter a bunch of formulas that I use over and over into either calculator. I would prefer some type of app where I can enter the formulas on a computer very quickly and then transfer them into the calculator. Possibly even some type of way where I can enter a few parameters in one place then use any formula to solve for unknowns.

While I have both calc's and can do basic functions on both, I am pretty green at doing more advanced things such as programming, etc. so please try and keep any recommendations to those where there isn't a huge learning curve and I can be entering formulas within a few minutes...

Thanks!

There are many types of specialized third party apps for the 89:

If you can't find the app you need, TI basic is pretty easy to learn.

There are a few different options for efficiently entering formulas on your calculator. One option is to use a spreadsheet program on your computer, such as Microsoft Excel, to input and organize your formulas. You can then transfer the formulas to your calculator using a USB cable or by manually inputting them. Another option is to use a calculator app on your phone or tablet, where you can easily input and save formulas for later use. Additionally, both the HP-50g and TI-89T have built-in programming capabilities, so you can create programs to input and solve formulas with ease. There are also online resources and tutorials available to help you learn how to program on your specific calculator. Whichever method you choose, it's important to practice and familiarize yourself with the process to become more efficient at entering formulas on your calculator.
