This one’s a keeper because 1) you can give it expressions in any form you want, which seems to me like something any graphing calculator should be able to handle and 2) it works offline, which also seems like something any calculator should do, since an app that has to ask a server to do calculations isn’t really a calculator, is it? The app is fast, the sliders nifty, and the layout streamlined. I put this to some pretty specific and odd uses at work (carpentry the explanation is lengthy and boring) and tried at least 20 different calculator apps in my search for just the right one. Just Super, But Could Use a Couple of Little Adjustments Visit to learn more and to see the free browser version of our calculator. Inequalities: Plot Cartesian and polar inequalities.Īccessibility: Read and edit math using a screen reader or a refreshable Braille display, and use audio trace to explore graphs and data through sound. It can handle square roots, logs, absolute value, and more. Scientific Calculator: Just type in any equation you want to solve and Desmos will show you the answer. Hold and drag along a curve to see the coordinates change under your finger. Tap the gray points of interest to see their coordinates. Points of Interest: Touch a curve to show maximums, minimums, and points of intersection. Zooming: Scale the axes independently or at the same time with the pinch of two fingers, or edit the window size manually to get the perfect window. Statistics: Find best-fit lines, parabolas, and more. Tables: Input and plot data, or create an input-output table for any function. Sliders: Adjust values interactively to build intuition, or animate any parameter to visualize its effect on the graph. There’s no limit to how many expressions you can graph at one time-and you don’t even need to enter expressions in y= form! Graphing: Plot polar, cartesian, or parametric graphs. Add sliders to demonstrate function transformations, create tables to input and plot data, animate your graphs, and more-all for free. Plot any equation, from lines and parabolas to derivatives and Fourier series. Price ~$12 new, ~$6 used.Explore math with the fast and powerful Desmos Graphing Calculator. This book covers angles, triangles, quadrilaterals, area, perimeter, Pi, circle parts, polyhedra, surface area, volume, nets, congruent transformations, and symmetry. You'll find answers to dozens of real questions from students who needed help understanding the basic concepts of geometry. The best part is that the explanations to math questions are accurate and clear. Math Introduces Geometry has a light tone, clear layout, and humorous cartoons by Jessica Wolk-Stanley. Math!Ī supplement to middle school geometry, Dr. Math Introduces Geometry: Learning Geometry is Easy! Just ask Dr. You can save, email, print, and embed your graphs.ĭr. You can use parameters with sliders, define your own functions and constants, graph inequalities, derivatives, and more. The discussions provided help the teacher in how to use them.Ī free, online graphing calculator that is incredibly easy and intuitive to use, yet very powerful. Users can drag a slider to modify a rate of change (cost per minute for phone use) and learn how modifications in that rate affect the linear graph displaying accumulation (the total cost of calls). These great interactive graphs illustrate the concepts of linearity and slope. Plot points before the mole eats the vegetables.į/algebra/graphing/default.htmĬreate graphs of functions but also allows the manipulation ofĬonstants and coefficients in any function so the user can explore the effects on the graph by changing those numbers. Enter the co-ordinates and click "check."Ĭlient_ftp/ks3/maths/coordinate_game/game1.htmĪ graphing tool that plots both functions and ordered pairs.Ī fun game about plotting points in coordinate plane. The players use coordinates to find their opponent's hidden quarks. hotmath_help/games/ctf/ctf_hotmath.swfĮeach player receives six quarks that they hide on a grid. Wait for the fly to land on the coordinate grid, then type its coordinates, and a frog will eat it. Move Billy Bug to the feeding place with given coordinates. You can customize the worksheets choosing the number of problems, workspace, border around the problems, and more. Students either plot points, tell the coordinates of points, plot shapes from points, reflect shapes in the x or y-axis, or move (translate) them up, down, left, or right.
