Path & Math 4+

■ Description ■
Take picture of any graph, outline data with your finger and get the best fit math formula.
After you paint few data points or the whole graph shape with your finger on the canvas grid, the app provides function formula definition and trend line for given data series automatically. App AI uses least squares regression function graphical solver for the best data fit.

■ How to control ■
Just paint data series on the canvas or type data with the keyboard, tap equal button and the artificial intelligence algorithm easily calculates function formula and plots trend line curve on the graph grid.
You can also add any image of a graph into the background and outline main data points with your finger.
Select from different function types and change function range to see effect of various prediction models on the final math formula and trend line in a graph.

■ Features ■
• Find formula for your math function.
• Paint data points with your finger.
• Add data to the canvas with the keyboard.
• Add any image into the background.
• The app features linear, quadratic, cubic, polynomial (up to 20th grad), power and logarithmic regression function models.
• Run regression analysis with the simple click and find easily the least squares fit.
• Create and share CSV data series with your project.
• Use calculated best fit formula in your Excel spreadsheet (just Copy & Paste to your xlsx file).
• Obtain RMSE – root mean squared error for each model.

■ For Who ■
Students, teachers, programmers, engineers, data scientists and all other math enthusiasts to demonstrate basic math behind function concepts.
For your math homework, SAT, GCSE, A-level, IB exam or prep for university admission test. Improve your knowledge to be well prepared.
