FAQ
What is Natural Logarithm?
Natural logarithm is logarithm with base e ≈ 2.71828, denoted as ln(x)
What is ln(e)?
ln(e) = 1, because e¹ = e
What is ln(1)?
ln(1) = 0, because e⁰ = 1
Why must antilog be greater than 0?
Because any power of e is positive, logarithm with base e can only be applied to positive numbers
