Read full description

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.
