ODE Solver

ODE Solver – Solve ordinary differential equations with ease.
• Solve systems of ODEs with initial boundary conditions using the 4th-order Runge-Kutta method.
• View results in interactive plots and lists, and export via email.
• Enter variables easily using the ”$” prefix (e.g., $x, $u, $t) and let the app handle the calculations.

Example: Typical Pendulum

dx/dt = $u
du/dt= -pi()**2/4*sin($x)-0.1*$u

• Supports a full set of operators (+, -, *, /, **) and functions (sqrt, log, ln, exp).
• Extensive trigonometric functions including sin, cos, tan, their inverses, reciprocals, and hyperbolic variations.
• Built-in constants: π, π/2, π/4, e.
• Smart entry fields:
• Background changes red/green to highlight unpaired/paired parentheses.
• Recognizes errors and displays warnings.
• Custom keypad and cursor arrows for smooth formula editing.

Perfect for engineers, students, and researchers who need fast, reliable ODE solutions on the go.
