## What is Numerical Solver?

Numerical Solver is a powerful numerical mathematics application designed to solve a wide range of mathematical problems directly on your iPhone or iPad.

Solve equations, differentiate functions, calculate integrals, plot functions and data, and now solve ordinary differential equations numerically.

Version 2.0 introduces ODE solving, supporting:

• Linear ordinary differential equations
• Nonlinear ordinary differential equations
• Initial Value Problems (IVP)
• Boundary Value Problems (BVP)
• Plotting of the numerical solution
• Evaluate the numerical solution at a given value of x

Numerical Solver is designed with a focus on numerical methods rather than symbolic mathematics. It provides practical numerical solutions while keeping the interface simple and easy to use.

Features include:

• Algebraic equation solving
• Systems of equations
• Linear and nonlinear equations
• Symbolic differentiation
• Numerical integration
• Function and data plotting
• Ordinary differential equation solving
• Initial Value Problems
• Boundary Value Problems
• Support for multivariable functions

Whether you are studying mathematics, engineering, physics, or another technical field, Numerical Solver provides a collection of numerical tools in one application.

Version 2.0 brings a major new capability to Numerical Solver with numerical solutions for ordinary differential equations.
