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.

please re-read my question.
How you got 0.999? Cos(2) is a real no. neither degree nor radian ..
its in degree mode
my question was when I convert the limits into then which mode should I use degree or radian?
you have taken 2 as degree , take radian not degree..
here integration is in coordinates system not polar system . So take radian not degree..
even in polar coordinate, we could measure the angle in either degree or radian, isn't it?
in all place , we use radian .
