Logarithm of InfinityWhat is the logarithm of infinity?log10(∞) = ?Since infinity is not a number, we should use limits:x approaches infinityThe limit of the logarithm of x when x approaches infinity is infinity:lim log10(x) = ∞x→∞...
The base b logarithm of zero is undefined: logb(0) is undefined The limit near 0 is minus infinity: Logarithm of 1 The base b logarithm of one is zero: logb(1) = 0 For example: log2(1) = 0 Logarithm of the base The base b logarithm of b is one: ...
