(Roll the mouse over the area above to see the correction in blue)
The chain rule is applied to the natural logarithm of a function g(x) as follows:
In this example g(x) = S/S0, so the first part of the derivative should be 1/(S/S0) and this should be multiplied by g'(x) = 1/S0 (think of S/S0 as the constant 1/S0 times S).
