Taking the Logarithm of ZeroDate: 08/11/2004 at 05:31:35 From: Vijay Subject: what is logarithm of zero? Why is log(0) not defined? Date: 08/11/2004 at 07:23:10 From: Doctor Ian Subject: Re: what is logarithm of zero? Hi Vijay, Remember that any logarithmic statement can also be expressed as an exponential statement and vice versa. Thus, if a b = c then log (c) = a b 3 For example, since 2 = 8, we can say log (8) = 3. 2 So if log (0) = a b then a b = 0 but there's no way to raise a number to any power and end up with zero. So log(0) is undefined. Does this help? - Doctor Ian, The Math Forum http://mathforum.org/dr.math/ |
