Variation of parameters: where is my mistake?

  1. Oct 23, 2016 #1
    1. The problem statement, all variables and given/known data
    Use the method of variation of parameters to find a particular solution

    2. Relevant equations

    3. The attempt at a solution

    You should type out the problem and your solution. Just posting images is strongly discouraged on this Forum.

    I second what Ray said. Although the image of your work that you posted is reasonably neat, many people post images that are blurry or messy or otherwise difficult to read. One of the main problems with work posted in images rather than as text here in the input pane, is that people responding can't insert a comment at the point where an error lies, but instead have to describe the location of the error.

    I am closing this thread. Please start a new thread with the problem and work shown directly in your post.
