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.

This is a special question in DE which you will see in higher classes. here given that question is only mean that are you know the shifting will also be the solution of given DE in certain conditions. such equations have infinite number of solutions at your stage, they only want to see that sometimes you also need to go through options. so you have to only do that put option in DE and if satisfy it then it will be the solution. remember always that if you are given solution as zero in option then you must check it because it may be your trivial solution. note that a solution of a DE always satisfy it's DE
