DEQ-visualization

A visualizer to show how differential equations can be numerically approximated using different Runge-Kutta numerical methods.

Quick Start

View this react app on netlify by clicking on the badge below.

Scroll down on the webpage to edit the function that is being approximated.

Here are the parameters and what they mean:

• n = number of steps to take. Is used to calculate h (step size) as
• x-initial = Initial value of x at starting point
• y-initial = Initial value of y at starting point
• x-final = point at which we are trying to estimate y
• epsilon = the threshold at which step-size is recalculated AND y-value is recalculated, essentially the error threshold beyond which approximation is recomputed
• Derivative function = this is the differential function that we are approximating

Supports:

• Euler's method
• Midpoint method
• Runge-Kutta 3rd Order (RK3) method
• Runge-Kutta 4th Order (RK4) method
• Runge-Kutta-Fehlberg (RK45/RKF) method
