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.

check ans is 1
why not this?
Have you made this series for this function show the process.
I just wrote down the Taylors theorem about=pi/2.
but you have to solve the function also na to get the exact ans.
vrna why would have they given the function..
for Taylor's expansion, the function must be continuous and differentiable, and at x=pi/2 the functions' derivative is 0, right?
yaa it might be because the function contains one series so first we should expand that.
