If you can imagine two curves(adsbygoogle = window.adsbygoogle || []).push({});

y = x^2

y=x

between y=[0,1] and x=[0,1] and you are asked to perform a double integration (compute the area encloed by the two curves) you can perfom this with x as the inner integral or y as the inner integral.

When x is the inner integral the limits are from y to sqrt(y)

When y is the inner integral the limits are from x^2 to x

My question is why do they go from y to sqrt(y) and x^2 to x and not sqrt(y) to y and x to x^2?

For a picture of the above see http://www.math.oregonstate.edu/hom...usQuestStudyGuides/vcalc/255doub/255doub.html final example
