In fact, if you begin a graphing problem but don't plot it, and then move to some other category, you'll lose that progress. The only exception is that there isn't a history of previous graphing problems. The app keeps a history of each section in the respective categories, so you can always return to Trigonometry, for example, to see those problems and answers even after you open a different area of the app. It gets confusing if multiple areas are mixed into one big calculator, like how some calculator apps work. The app is chock-full of functions for several areas of math, so it's great that each category has its own section, like one for basic math and another for linear algebra. It's free to see answers, define terms, and plot points on a graph, but if you want step-by-step work and detailed explanations, you'll have to subscribe to the Premium version. It covers basic math, pre-algebra, algebra, trigonometry, precalculus, calculus, statistics, finite math, linear algebra, chemistry, and graphing. Mathway might be the only calculator you need.for everything. ![]() Its picture-taking abilities aren't as great as similar appsĭoesn't save graph information when you exit You can use this free calculator app from an Android, iPhone, or iPad, as well as directly from the Desmos website. If you're using it from a computer, you can share a graph through a special link, as well as download an image version. They don't show up on the graph.ĭesmos can also store images on the graph, plot data points via tables, disable the grid lines, label the x and y-axis, and quickly undo and redo any changes made to the expressions. Notes can be added next to any of the expressions to remind yourself of why you added something to the graph or to help you study. If you tap an area of the graph, it will highlight the expression to show you exactly which one is responsible for that specific area of the graph, which is great for learning. ![]() It also supports function transformations via slider buttons, so instead of adjusting the expressions manually, you can just slide the bar left or right to quickly decrease or increase the value. One of the major differences in this graphing calculator app versus some of the others you might find is that it doesn't limit the number of expressions you can graph at once. The small keyboard can sometimes be hard to useĭesmos is the absolute best free graphing calculator for Android, iPad, and iPhone, and because it works online, too, you can save your graphs and edit them anywhere.
