been working on these all week some help please..
9) 3y''-6y'+30y= 15sinx+exp(x)tan(3x)
10) y''-2y'+y= 4x^2 -3+ Exp(x)/x2. Homework Equations
Variations of parame
Method of undetermined coefficients
thoughts:
i think that you need to split the eqtuaion into 2 parts. Using variation of parameters on 3y''-6y'+30y=exp(x)tan(3x).. and using method of undetermined coefficients on 3y''-6y'+30y=15sinx.. i have tried this approach on both problems with no luck.
