DifferentiationCalculator vs Equation

This app calculates the analytic formula of the first derivative of a given function. Derivative represents a rate of change of a function with respect to an independent variable. This app enables to differentiate a function that depends on more than one independent variable (called here a multi-parametric case) by considering these variables separatelly. To do so, one must declare a name of independent variable with respect to which a given function is differentiated. During differentiation, the rest of variables is kept constant. The derivative found on the basis of the obtained analytical formula can be compared with the derivative found numerically. The obtained results can then be depicted in plots. In order to plot a multi-parametric case, all remaining independent variables must be set by the user. To make this app more didactic, it is possible to track and practise intermediate stages of searching for the analytic derivative. All these steps can be performed by the user himself. In this way, the final formula of the derivative sought will become more understandable.

The EquationSolver is carefully designed to be a simple and elegant app. Easy to use, easy to understand, simple and effective It solves system of linear equations, simultaneous linear equations (no limit on the number of equations). It also teaches you the steps to solve such systems. To find a solution, it uses Matrix inversion method or LU decomposition method when inverse is not possible or complicated. The equations are beautifully presented in both: 1) Set of individual equations form 2) Matrix-vector product form. You can also share the beautifully written solution It automatically saves your hard work locally on your device so you can come back and pick up from where you left off as your great effort will not be lost. This is a perfect app if you are a student learning to solve these kind of equations. There is also a Study page to help you with learning some important linear algebra formulas. This is an app for all student groups. From high school to college to university students. Be creative. Enjoy the app!
