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 because, when we find the differential equation then only parameter is removed no the known constants. suppose, if this is not given that a and b are known constant then we need to remove them too. the known(given) constant means that we know there value, and we know that to find the differential equation we remove only arbitrary constant(which will occur during finding the solution of a differential equation). here the interesting fact about that differential equation is it is self orthogonal.
