Say you have use the Runge Kutta-4 (RK4) Method to solve a 2. order Differential Equation such as :
| y”+5y’+y=Sin(x) y'(0)=-1 y(0)=1 h=.5 solve until y at x =1 |
Use the Numerical Made Easy app at TI89.com option F3 7 :
Solve the Differential Equation for y” and enter above information as follows:
After entering just press ENTER
to view the solution:
It is very easy to solve approximate such 2. order Differential Equations using the Runge Kutta Method. Very easy and always right.
