How to solve the 1. order Diff Eqn: (3y+2t-2)dt + (10y+3t-1) dy = 0 with y(-1)=2 Just replace every t by x and enter the D.E. and initial conditions under F1 C as shown. To view more steps on how to solve an exact Diff Eqn enter it under F1 6 . Voila!!
There are 2 ways to solve this Differential Equation: 1) Since it is linear in y use F1 : Linear in y enter P=-x^2 and Q=2x^3 press Enter . Using an Integration factor will yield the answer. 2) Rewriting it as y’=2x^2+x^2*y=x^2*(2+y) shows that the method of separating the variables will work as well, That… (read more)

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)
