For \int\limits^1_2 {5e^(1/x) dx.} \, dx find the trap sum and midpoint sun when n=4. Which I did, I got:

T4 = 10.15946

M4 = 10.071034

But I'm stuck on the next part:

How do I estimate the errors in the approximations of what I have above? (because subtraction isn't it)

And then

How large do we have to choose n so that the approximations Tn and Mn to the integral are accurate to within 0.0001?
