Expert Solution
Step 1: ''Introduction to the solution''

The  given equation  is   open parentheses 25 y plus y apostrophe apostrophe close parentheses equals 0

                             that  is, open parentheses y apostrophe apostrophe plus 25 y close parentheses equals 0............ left parenthesis 1 right parenthesis

It  is  given that y equals sin left parenthesis L x right parenthesis space is a  solution  of the  given differential  equation(1).

We  have  to  find  the  values  of  L for  which  y equals sin left parenthesis L x right parenthesis  is  a  solution of  the  given differential  equation(1).

Since,  we  want non-trivial solution  of the  given differential  equation, it follows  that y not equal to 0 for  any values  of L.
