Que 1:

Sol:  Region bounded  by
x = 0, x = 1 and y = x, y = 1
Now we evaluate the integral by hanging the order of integral

Que 2: The value of the double integral

Sol:  Region of integration is bounded  y=0, y = x and x = 0, x = π
 changing the order of integration


= 2

Que :-3 Evaluate

Sol: 

Que 4:- Change the order of integration in the double integral

Sol:  Domain of integration is bounded  by the following curves

point of intersection of the curve y =2 - x² and y = -x we get when

So (-1,1 ) and (2,-2 ) are the points of intersection.
Now the given integral modify by changing the order of integration we get

 Que 5:- Changing the order of integration of

Sol:
The region of integration is bounded by y = 0, y = x, x = 1, x = 2 after changing the order the integration changes to
