2 6 Chain Rule Example 1 E 2x Youtube There's no ln a in the derivative of e u Well, actually, there is However, since a = e, ln a = ln e which = 1, so we don't bother to write it Note4 Notice the difference between the derivatives of y = ln u and y = log a u Same as in Note3 the ln a is missing in the denominator when the base = e (ln u) because ln e = 1Finding the derivative of a logarithm with a base other than e is not difficult, simply change the logarithm base using identities If given a function \log_a(b), change the base to e by writing it as \frac{\ln(b)}{\ln(a)} E x derivative rules vs
