Question

Suppose that a fourth order differential equation has a solution y = -3e^5x x cos(x). (a) Find such a differential equation, assuming it is homogeneous and has constant coefficients. (b) Find the general solution to this differential equation. In your answer, use c1, c2, c3 and c4 to denote arbitrary constants and x the independent variable. Enter c1 as c1, c2 as c2, etc.

Step 1

We can see that the function is a combination of exponential and trigonometric functions. The derivative of an exponential function is itself and the derivative of cos(x) is -sin(x). Let's find the fourth derivative of y: y' = 3Sxe^(Sxx) cos(x) - 3e^(Sxx) Show more…
