FutureStarrFraction on Graphing Calculator
This tool allows you to graph and plot scientific functions such as the "y=" and "y^2=" functions. It also graphs polynomials and has a histogram and boxplot feature.
You can also use the FRAC menu to enter mixed numbers on your TI-84 Plus calculator. As with entering fractions, press ALPHA and then Y= to bring up the FRAC menu. Then use the arrow keys to select the second option in the menu, Un/d. This brings up the template for entering a mixed number. Enter the whole number first, and then use the arrow keys to mouse through the template as you enter the numerator and denominator too.
GraphNCalc83 uses touch, color and blazing speed to handle your math problems. The familiar calculator keyboard, arrow keys and functions are enhanced with full touch input for all graphs, editors and menus. Enter calculations in natural textbook format. Enter fractions and view result as fractions. Trace graphs with your finger. Zoom in and out with a pinch. Explore regressions with a tap on the screen. Scroll through the list, matrix and calculation history with a swipe. Tap the ? key for help. Written using the latest 64 bit math libraries, GraphNCalc83 harnesses the amazing computing resources of the iPhone and iPad to provide a colorful, fast and fluid experience. Graphs scroll, glide and zoom smoothly. Matrix, statistics and BASIC programs run 500x times faster than traditional calculators. (Source: apps.apple.com)
This is such a great app to use instead of a super expensive graphing calculator. I recommend it every year to my students. It’s fabulous for those on-the-spot study sessions at the coffee shop when you have forgotten your calculator. Many of my students have switched to it as their primary calculator. The functions are the same and the control over graph zooming is a simple pinch method. To identify mínima and máxima you just slide your finger over the graph until the color changes. no left and right bounding required. As an instructor, I use it with my iPad and OneNote during lecture. My lecture notes are projected to the overhead screen as I write them in OneNotes. When I need to demonstrate a concept on the calculator I slip it out by swiping left and a small version of the calculator is overlaid on my notes. When I am done, a swipe right allows me to return to only the notes screen. Students are able to watch my key strokes in real time. (Source: apps.apple.com)
