• Solving Trigonometric Equations

  Solve equations like 2 sin x = 1: find one angle, use the unit circle to find every solution in one cycle, and add multiples of the period to get them all.

• Inverse Trigonometric Functions

  Why sine, cosine and tangent need a restricted domain before they can be undone, what arcsin, arccos and arctan return, and how to solve trig equations in context.
