Math-Solver for Students, Scientists, and Engineers
⬤ Enter a problem in plain text ▶ Press the Solve button ⬤ Get a numeric solution
Embracing our vision, we offer a vibrant, free version of our premier user-friendly Math Solver.
The PolymathPlus solver is available as a web application. A link to the solver becomes visible on the left menubar after login. We are encouraging users to switch to the online version while gradually phasing out support for the Windows desktop application.
Our internal algorithms have been extensively used over the years by many engineering faculties in universities across the world. Students and professionals will appreciate the ease of use and the comprehensive solution reports of our application.
PolymathPlus can solve linear equations of any size. The number of equations should be equal to the number of unknown linear variables. Here's an example of 3 linear equations to be solved simultaneously:
Below are the equations entered into the PolymathPlus problem input text box (note that the # sign indicates user remarks and is being ignored by the program):
When solving simultaneous nonlinear equations, the equations have to be written as root expressions (expressions that are equal to zero in the solution). In addition, an initial guess should be provided for each nonlinear variable.
Below is a sample problem and data entry for solving 2 nonlinear equations:
When entering the problem into PolymathPlus, we should enter the root expressions, each associated to a nonlinear variable function. We should also provide an initial estimate for each nonlinear variable. In the example below, we have 2 nonlinear variables x and y, hence 2 root functions, and we provide an initial guess of 1 for both x, and y.
Note that we may also define any number of auxiliary expressions, to simplify long expressions, in this example we define
a as an auxiliary expression:
In case we only have one nonlinear equation to solve (with any number of auxiliary expressions), we need to provide a min/max estimates for the nonlinear variable. For example, below is a PolymathPlus program for solving one nonlinear equation where we need to evaluate
Entering and solving ordinary differential equations with PolymatPlus is simple.
Consider this set of equations to be solved:
Given the initial conditions x0=1, y0=4, at t0=0, and having the integration finish at tf=1,
the text below should be entered into PolymathPlus:
The following alternative compatible syntax can also be used for the same problem:
The solution will be displayed in a tabular format and will also include the integration chart:
PolymathPlus supports curve fitting for polynomial, multi-linear, and nonlinear regression. The report evaluates the model variables, generates a regression chart, residual plots, and provides statistics on the accuracy of the model.
Here is an example of the data entry required for solving a linear regression model for a given set of data points.
We solve a polynomial regression model with the order of 1 (hence linear regression) which best fits the linear equation matching the given data points.
polyfit <x> <y> <order> [origin]
Below is an example of a data entry for solving nonlinear regression model for a given set of data points. The model variables to be found are
b, for which we should also provide an initial guess.
