Question

A) Make the largest possible linearly independent set of functions that are annihilated by the differential operator $((D-3)^2 + 25)^2$. You do not need to add arbitrary coefficients or prove that the set is linearly independent. B) Find an annihilator for $cos(2x)e^{-x}$ write an expression of the form $y = c_1y_1 + c_2y_2 + ... + c_ny_n$ (using arbitrary coefficients on all terms) of a general solution to $((D-3)^2 + 25)^2[y] = cos(2x)e^{-x}$.

Step 1

The characteristic equation is obtained by setting the operator equal to zero: ((D-3)^(2)+25)^(2) = 0 Expand the expression: (D^(2) - 6D + 9 + 25)^(2) = 0 (D^(2) - 6D + 34)^(2) = 0 The characteristic equation is D^(2) - 6D + 34 = 0. Show more…
