1. anonymous

$\int\limits_{0}^{1}\int\limits_{1}^{x}1dydx$

2. anonymous

can someone explain how to change the order of integration ?

3. anonymous

yes there is formula for double integrate

4. anonymous

i think y is from 1 to x

8. anonymous

then looking at x from 0 to 1

9. anonymous

?

10. anonymous

anyways once you have the graph we know that y must be from 0 to 1 right?

11. anonymous

yes

12. anonymous

then x would have to be from 0 to what? (in terms of y)

are you sure that integral is not$\int_0^1\int_x^1dydx$?
