Textbook Problem

Write a trial solution for the method of undetermined coefficients. Do not determine the coefficients.

**13.** *y"* – *y' –* 2*y* = *xe ^{x}* cos

To determine

**To write:** The trail solution for the method of undetermined coefficients.

Explanation

**Given data:**

The differential equation is,

Consider the auxiliary equation.

Write the expression for the complementary solution for two distinct real roots.

Substitute

If Right hand side (RHS) of a differential equation contains a product of an exponential function, a cosine function, and n^{th} order polynomial, the trail solution of the differential equation also should be a product of these corresponding choices. So, the trail solution for this case can be expressed as follows
