Maths Info And Solvers provides general mathematical information sheets plus a range of equations solvers/calculations in the maths fields of Geometry, Statics,Series,Proportional Lengths,Interest,Areas and Volumes. Also operations between square matrices can be performed (multiply,Addition,Subtraction, Transpose) as well as Linear Equations solving using the Jacobi Interation method.General settings can be made for the program and for the Jacobi Interation method. The App is easy to use with a tab/swipe layout design. The About/Help tab offers a simple web browser. For the linear solvers using the Jacobi method requires setting the initial variable estimates and the number of interactions. On display of the results a Error value is also displayed next to the variable value. The error is the difference between the displayed and previous variable value. Generally the smaller the error value the more accurate is the result. Matrices can be saved, emailed, downloaded to file and reopened. Features a web browser view to the main website for further help details. The Web browser can be used for general internet use. Offers internet help on the product and general application information. Application Permissions : Read/write to SD Card.
