What is ln 0.01?

Answer

ln 0.01 ≈
−4.6052

ln is the natural log, base e ≈ 2.71828.

≈ — the logarithm is irrational; the value is rounded to 4 decimal places.

ln 0.01 is the power you raise e ≈ 2.71828 to, to get 0.01: ey = 0.01.

e⁻⁵ ≈ 0.0067 < 0.01 < e⁻⁴ ≈ 0.0183, so −5 < ln 0.01 < −4

Answer point ≈ (0.01, −4.6052).

The curve y = ln x passes through (1, 0) and (e, 1) and rises: for x > 1 the log is positive, for 0 < x < 1 negative.

What is the difference between ln 0.01 and log 0.01?

ln 0.01 is the logarithm to base e, log 0.01 is to base 10: ln 0.01 ≈ −4.6052, log 0.01 = −2. One is the other divided by ln 10: log 0.01 = ln 0.01 / ln 10 = −2.

What does log without a base mean?

At school and on a calculator, log x without a base is the common log, base 10: log 100 = 2. In Python, math.log(x) is the natural log ln x; in Excel, LN is the natural log and LOG is base 10.
