Differential Equation Solving System

A Differential Equation Solving System is an equation solving system that can apply a differential equation solving algorithm to solve a differential equation solving task.

• AKA: Differential Equation Solver.
• Example(s):
  • Taylor Series Method System.
  • Euler Method System.

import math import matplotlib.pyplot as plt

1. \ Initial conditions

y0 = 2.0 \# Time step and final time dt = 1.0 # days tf = 364 .0 # days \# Empty lists to hold the time and solution tt = [ ] yy = [ ] \# Append initial values tt.append (0.0) yy . append (y0) \# Parameters of our equation a = 0.01 omega = 2.0*math.pi/365.0 \# Iteration while tt [−1] <= tf : r = a*yy[−1]*(1+math . sin(omega*tt[ − 1 ])) yy.append(yy[−1]+ r*dt) tt.append (tt[−1]+dt) plt.figure(1) plt.plot(tt,yy,'.') plt.xlabel('Time[days]') plt.ylabel('Rats[rats]') plt.title('Euler Solution') plt.show( )
