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.

f(x)=sinx-x f'(x)= cosx-1≤0 so f is motonic decreasing function
please check this example sir
what's ur dabut
sinx increase x increase but sinx-x is decreasing
here this show difference of two increase is not increase
sir in example... sinx - x is not monotonic but it is monotonic decreasing
so clear it
