This application is doing studies of mathematical functions, calculation of integrals, searching of antiderivatives and solving of equations and inequalities.

For function study, the function, e.g. ln(3x^2-1), has to be specified in the first text box. Note that you can use the camera to take a picture of the function directly. A study interval can also optionally be given (e.g. [3;+∞[). By then clicking on "Go!", the analysis is performed (domain of definition, derivative, limits, asymptotes equations, table of variations, graph). The result is a PDF file. An internet access is required. In case a bad function or interval is entered or if a problem occurs while trying to connect to the internet, a descriptive error message is displayed.

For integrals calculation, a function has to be specified in the first text box (you can also use the camera to take a picture of the function or the integral). The lower and upper bounds of the integral have to be given in the second text box as an interval (e.g. [3;+∞[). If no interval is specified at the time the "Go!" button is pressed, antiderivative is calculated. As for function study, result is a PDF file. An internet access is required. In case a bad function or interval is entered or if a problem occurs while trying to connect to the internet, a descriptive error message is displayed.

For equations or inequalities solving, the left hand side of the equation or inequality, e.g. x^2 + x + 2, has to be specified in the first text box. The right hand side, in the second text box, is optional and will be set to 0 if left empty. Then, you'll have to choose the = sign (which is the default) for an equation or the <, ≤, ≥ or > sign for an inequality. Again, you can use the camera to take a picture of the equation or inequality. After having pressed the "Go!" button, the solutions of the equation or the inequality (if any) are given in a PDF file. In case a bad equation or inequality is entered or if a problem occurs while trying to connect to the internet, a descriptive error message is displayed.
