The Attempt at a Solution
the above integral i can do with no problem, but changing the order of integration give me a totally different answer and need to know if i am doing it correct
First off
[tex]
\displaystyle\int^1_0 \int^{e^x}_{1}dydx = e^1 - 2
[/tex]
To reverse the order of integration i get:
[tex]
\displaystyle\int^{e^1}_1 \int^{ln(y)}_{0}dxdy
[/tex]
which gives me 1 which is wrong
Before i post how i went about my solution I want to know if i am doing my limit right?
