SUMMARY

The discussion centers on solving the differential equation y'(x) + x*y''(x) = A*x using the method of undetermined coefficients (UDC). Participants confirm that the equation can be approached by taking an antiderivative of the left side to initiate the solution process. The method of undetermined coefficients is recommended for finding a particular solution to this equation. The conversation emphasizes the importance of recognizing the structure of the equation before applying the UDC.

[d]/[/dx](x*[dy]/[/dx]) = A*x

is that equivalent to saying y'(x) + x*y''(x) = A*x

then use the method of undetermined coefficients to solve it for y?

Just need a start, not the answer. Thanks.

You have an exact derivative on the left side as it stands. Just immediately take an antiderivative to get started.
 
ah,
Thanks.
