## Homework Statement

Reverse the order of integration?

Original has it in the form of dy dx, 0<=x<=ln6, 1<=y<=e^x.

I made it dx dy, with 1<=x<=e^y, 0<=y<=ln6

Is this right?

Draw a graph. x ranges between 0 and ln(6) so draw two vertical lines there.

Now, what are the lowest and highest value of y in that "triangle"? Saying that x< ln 6 does NOT mean y< ln 6. y is not x!

Imagine a

[itex]y= e^x[/itex] does NOT give [itex]x= e^y[/itex]!! Solve [itex]y= e^x[/itex] for x.
