Question
Construct an equation such that y = C1e³x
cos x + C2e3* sin x is its general solution.
Transcribed Image Text:Construct an equation such that y = C1e³x cos x + C2e3* sin x is its general solution.
Expert Solution
Step 1

To determine the differential equation from the solution 

  1. Check the number of constant in the solution. 
  2. The order of the differential equation is same as the number of constant in the solution 
  3. Differentiate the solution as many time as the number of constant as there in the solution. 
  4. Rearrange the equation in such a way that the differential equation will form.
