Backwards Euler Method for 1. order Differential Equations

TI89 : Backwards Euler Method for 1. order Differential Equations

Solve Cauchy Euler Differential Equation Step by Step on the TI89

2. Order Cauchy Euler Differential Equations are of the format x^2*y” + b*x*y’ + c*y=f(x) Homogeneous solutions are linear combinations of format c1*x^m1 + c2*x^m2 where m1 and m2 are zeros of a corresponding char. equation. Good news for TI89 users: This type of Differential Equation can now be solved step by step using Differential… (read more)
