In paper 4, we count the squares and the convert them to the appropriate units. So, I don't think that you really need to integrate.
Anyways, you don't have to find the area of curves but the area of a triangle...

for example, if you have to find log x, where x = y +/- z
you find the max. value, which is log (y + z)
and the best value, which is log y
the difference between these two values is the error.

Can you please explain this?! I don't get it..
Lets say we have: 3.5 ± 1.0 , and we want to find the log and absolute error.
The log would be 0.544 but what would be the absolute error?! If I use the above equation you gave, I'll get 0.012 but the MS answer is 0.017!!
How do you do this?
