Double integral of cos (y^2) dy dx, where y=1 , y=x, x=0, x=1 are the bounds

Change the order of integration. The region over which you're integrating can be equivalently described by the set of points in the plane, .

Then the integral becomes

Substitute , :

step-by-step explanation:

i need to answer questions so i dont know but i think its the first one because it goes up but a consent rate

it would be:
