Four-figure mathematical tables for board exam use. Select a table to view logarithms, antilogarithms, natural trigonometric functions, and standard ratios.
Choose Logarithm, Antilogarithm, Natural Sines, Cosines, Tangents, or Trigonometry Ratios above.
Four-figure log₁₀ table — rows 10–99, columns 0–9, mean differences 1–9
Four-figure antilogarithm table — rows .00–.99, columns 0–9, mean differences 1–9
0°–90°, intervals of 6′ (0°.1), mean differences 1′–5′ (add)
0°–90°, intervals of 6′ (0°.1), mean differences 1′–5′ (subtract)
0°–89°, intervals of 6′ (0°.1), mean differences 1′–5′; differences cease near 90°
* Mean differences cease to be sufficiently accurate beyond 77°.
