Graphing Calculator 84 vs Accelab

The graphing calculator provides a UI similar to a real 84 graphing calculator. ◉ Graphing Calculator - Supports function, polar, and parametric graphs. - Press MODE and select Graph mode, then press Y= to open the graph editor. Press GRAPH to draw the functions. - Interactive and manual tracing modes. - Shows intersections, roots, and extrema (local maxima and minima) of function graphs. - Shows derivatives of function graphs. - Shows tangents to function and polar graphs. - Best‑fit line for a set of points. - TABLE generates a table of values for the selected graph. - CALC computes min, max, d/dx, and integrals of the selected graph. ◉ Scientific Calculator - Includes a computer algebra system for symbolic calculation. - Supports the functions you use on 83 and 84 graphing calculators. - All basic and advanced math functions: complex numbers, probability, angles, relational operations, logic operations, and matrix and vector operations. - Users can define custom calculator functions. ◉ Equation Solver (press ALPHA ENTER to open the SOLVER menu) - Solves any equation with Auto Solver mode and can provide symbolic roots. - Solves quadratic, cubic, quartic, and quintic equations. - Solves systems of equations with up to 5 variables. ◉ Statistics - 1‑Var Stats: calculates 1‑variable statistics. - 2‑Var Stats: calculates 2‑variable statistics. - LinReg(ax+b): fits a linear model to data. - QuadReg: fits a quadratic model to data. - CubicReg: fits a cubic model to data. - QuartReg: fits a quartic model to data. - LinReg(a+bx): fits a linear model to data. - LnReg: fits a logarithmic model to data. - ExpReg: fits an exponential model to data. ◉ Inferential Statistics and Distributions - Z‑Test, T‑Test, 2‑SampZTest, 2‑SampTTest, 1‑PropZTest, 2‑PropZTest, Z‑Interval, T‑Interval, 2‑SampZInt, 2‑SampTInt, 1‑PropZInt, 2‑PropZInt, Chi‑square Test, Chi‑square GOF Test, 2‑SampFTest, LinRegTTest, LinRegTInt, ANOVA. - All distribution functions, including Normal, Student’s t, Chi‑square, F, binomial, and more. ◉ Get Calculator 84 Premium Upgrade to the Premium version to access all the features above, including advanced math functions, statistics, inferential statistics and distributions, scanning math with your camera, and more.

Accelab is an educational app that helps students collect the data for three physics labs: a cart on an air track, a projectile, and circular motion. Choose the experiment first, then one of two ways to measure it: ⋅ Camera (recommended for the air track): film the cart with your iPhone, or choose a video you already have. Mark any known length in the shot, and Accelab follows the cart through the video. It can follow an object in flight, or a marker going round, the same way. ⋅ Sensor: attach your iPhone to the cart, or lay it flat on a turntable, and measure its motion with the built-in sensors. Accelab can help you: ⋅ Make sure that your air track is set up with the angle you chose ⋅ Collect the distance-time data of your cart as it travels down the air track ⋅ Collect the x and y position of a projectile against time, with your iPhone levelled first ⋅ Collect the position and angle of a marker going round a circle against time, filmed from above ⋅ Measure the angular velocity and the centripetal and tangential acceleration of a turntable against time, with your iPhone lying on it ⋅ Check the tracked points on the video and correct any of them by hand ⋅ Create a CSV file with the collected data, or copy it straight into Desmos: all of it, or just the two columns for the graph you want to plot ⋅ Save a photo of the run with every tracked point marked on it ⋅ Come back to your finished runs later in Past Runs Accelab is an open-source project developed by a student.
