What to Focus On

  • Trigonometry studies sides and angles of triangles.
  • An angle is a measure of rotation.
  • Anticlockwise rotation is positive.

  • 1 degree = 1/360 of a revolution.
  • 1 degree = 60 minutes and 1 minute = 60 seconds.
  • 1 radian is defined using arc length in a unit circle.

  • cos x and sin x are defined using the unit circle.
  • cos^2 x + sin^2 x = 1 for every x.
  • Quadrantal angles are multiples of pi/2.

Common Mistakes to Avoid

Sin x = 0 at odd multiples of pi over 2, and cos x = 0 at multiples of pi.

Tan x and sec x are undefined at multiples of pi, while cot x and cosec x are undefined at odd multiples of pi over 2.

All trigonometric functions have the same period of 2 pi.
