Hi,

I was just wondering if the set up for this problem; integrate f(s,t)=e^slnt over the region in the first quadrant of the st-plane that lies above the curve s=lnt from t=1 to t=2

is:

integral(t=1 to t=2)integral(s=ln1 to s=ln2) of e^slnt

If that's not the right set up what am I doing wrong

Hi s7b! :smile:

(have an integral: ∫ :wink:)
integral(t=1 to t=2)integral(s=ln1 to s=ln2) of e^slnt
No … you can either start ∫(t=1 to t=2), or start ∫(s=ln1 to s=ln2) …

but then you have to ask what are the limits of s at each value of t (or vice versa) :smile:
