Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

your solution is correct. but in book solution is done by the method of variation of parameter. and the answer matches exactly as given in question
![eduncle-logo-app]()
so I am asking is there any difference in the solution if we use two different methods to solve a differential equation
![eduncle-logo-app]()
no, use any method answer is same always. if there any difference in answer then it may be possible we do some mistake in calculation or rounding mistake or there is misprint.
