This app presents an equation with two variables and an x vs. The TI-84+ will then graph and trace them. You can choose from any of the four conic sections (circle, parabola, ellipse, and hyperbola) to input your equation. ConicsĪs any advanced algebra or pre-calculus student will tell you, conics sections can be a confusing topic. This is especially good for learning how the slope and y-intercept interact with lines, and reinforces similar concepts with quadratics and absolute values. An animated trace of your guess appears, hopefully retracing the original graph. A graph appears on the screen, and, it’s your job to guess its coefficients. This app is fantastic for algebra through pre-calculus students learning how to graph lines, parabolas, and absolute value functions. The TI-84 plus silver edition even comes with stacks of ACT and SAT practice problems preloaded onto it. You can use the preloaded cards, dowload additional stacks of cards from the Texas Instruments website, or even create your own cards.

Studycardįlash cards go high tech with this app. You wouldn’t want to get in trouble for playing this in class. It includes 4 games, Dino Puzzle, Puzzle Frenzy, Pegs, and the incredibly popular Block Dude. This is the ultimate puzzle and game app for the TI-84+. The simultaneous equations solver solves systems of equations from the intersection of two lines up to 10 equations and 10 unknowns. The polynomial root finder ( lesson here) can solve simple linear equations, quadratic equations, or any polynomial up to a degree of 10 with fractions or decimals and real or imaginary answers. The TI-84 doesn’t have all of the algebra capabilities of a TI-89 or TI-Nspire CAS, but “PlySmlt2” helps make up for some of that. (NOTE: These apps should all work on a TI-83+, but the memory is very limited so they won’t all fit on the calculator at the same time). If they’re not preloaded on your calculator, all of them are available free from the Texas Instruments website. Here are my favorite 6 apps for the TI-84+. That said, there are a few true gems in there, a combination of puzzles, games, and apps that will just plain make your math class easier. In fact, the TI-84 Plus (especially Silver Edition) comes loaded with a lot of junk you’ll probably never use because many of the preloaded apps are for languages you don’t speak.

If you’ve just picked up a new TI-84 plus, one of your first questions is probably, “What are the best apps this thing?” There are many. What Are the Best Apps for the TI-84 Plus?
