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.

as cos is an even function it does not change the nature of function but sin is odd function it changes the Nature of function so for convenience we take cos as the function is not affected by taking cos that's why always we use cos when we have to choose from our side
but is taking sin not allowed i mean if im taking sin should my answer be called wrong
not it is not wrong logically but in order to match ans or considering the standard form we used to take cos if you will take sin there will be just phase difference
