What to Focus On

  • 1 degree is divided into 60 minutes.
  • 1 minute is divided into 60 seconds.
  • Decimal degrees can be converted step by step into degrees, minutes, and seconds.

  • Trigonometric tables give approximate values of sine, cosine, and tangent.
  • The values are given for angles from 0° to 90°.
  • The values are correct up to four decimal places.

  • The table has 12 columns.
  • The first column contains degrees from 0° to 90°.
  • Ten columns are headed by minute values such as 0', 6', 12', 18', 24', 36', 42', 48', and 54'.

Common Mistakes to Avoid

Decimal degrees can be read directly from the table without converting the fractional part into minutes and seconds.

One degree has 100 minutes because decimal numbers often use base 10.

The ten minute columns in the trigonometric table are a complete 0' to 54' list in steps of 6, so 30' must also be present automatically.
