https://en.wikipedia.org/wiki/Analytical_Chemistry
Analytical chemistry studies and uses instruments and methods used to separate, identify, and quantify matter. In practice, separation, identification or quantification may constitute the entire analysis or be combined with another method. Separation isolates analytes. Qualitative analysis identifies analytes, while quantitative analysisdetermines the numerical amount or concentration…

A classical method for integrating ODEs with a high order of accuracy is the Fourth Order Runge–Kutta (RK4) method. This method uses four points k 1, k 2, k 3, and k 4. A weighted average of these predictions is used to produce the approximation of the solution. The formula is as follows:
