Natural Log of 0.4 (ln 0.4)

What is ln 0.4?

Answer

ln 0.4 ≈

−0.9163

ln is the natural log, base e ≈ 2.71828.

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

ln 0.4 is the power you raise e ≈ 2.71828 to, to get 0.4: e^y = 0.4.

e⁻¹ ≈ 0.3679 < 0.4 < e⁰ = 1, so −1 < ln 0.4 < 0

Answer point ≈ (0.4, −0.9163).

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.
