@SanketBiradar
sorry but i didnt understand anything
can explanation be more detailed

@NishantThakre
See the graph of xsinx us simply a sinosudal wave along line y=x.....now it's inverese will be it's mirror image about y=x..so now I have the graph of inverse of itNow all I wanted was slope of tanget at π to the inverse graph and slope of normal at 2π to the inverese graph and then all we had to do was find area
Now for slope of tangent to inverese funcn at π and 2π I used the property of inverse
Now I know the bounded region .....then I found the area of half the loop of sine wave by finding area of f(x) in the interval and subtracted the area of lower trapezium from it so I got area of half loop of sine wave in that interval and then used all the things I found to find the area
