nevermind, i figured it out myself

for Nth degree differential equation, there is a different formula. http://img256.imageshack.us/img256/8756/dif2.jpg Here, W(t) = W (y1,y2,y3,...,yn)(t) and Wm(t) is the determinant obtained from W by replacing the mth column by the column (0,0,...,0,1)

Homework Statement Find the particular solution to the differential equation using method of variation of parameters: 4y''-4y'+y=16e^(t/2) The Attempt at a Solution Set 4y''-4y'+y=0 then the homogeneous solution is: y= c1*e^(t/2)+c2*te(t/2) set y1= e^(t/2), y2= te^(t/2)...
