MathAlly Graphing Calculator + has all the features of the freeversion plus: -View Step-by-Step how the answer was calculated byclicking on the result (see screen shot). -Parametric and Polarcoordinate graphing. -New All Cartesian graph mode which can graphany equation even if it can't solve for x or y. -Create customkeyboards. -Create custom keys as expressions or functions. -Savegraph setups and screenshots. -Create workspaces to organize andpermanently save calculations. -Additional matrix operations:reduced row echelon form, LU and QR decomposition, eigenvalues, andeigenvectors -Graph up to 6 equations (free limits you to 3). -NoAds -Since there are no ads, no internet permission is required. Q.How do I view the Step-by-Step screen for a problem? A. First enterthe problem into the calculator and hit enter to see the result.Then click on the result. Make sure you are clicking on the resultand not its input, as clicking on its input will paste the inputinto the current entry field. Also, Step-by-Step must be enabled inthe settings when the result is calculated. By default Step-by-Stepis enabled. If you are not completely satisfied with your purchaseand you email me at [email protected] within 14 days of yourpurchase, I will give you a refund. Please include your ordernumber in the email. (Google play only gives you 15 minutes toautomatically get a refund, I think this is too short). You canonly request a refund once. If you find any bugs or have questions,please email me. Explanation of permissions: Storage - Needed forapp to be able to read/write to external storage. This allows usersto transfer custom keyboards between devices.
