Solving Trigonometric Equations Worksheets

Practice exact trigonometric values and identities with angle units and domains stated.

Before you begin

Use radians, the unit circle and exact special-angle values.

Worked example

Solve 7sin θ = 0 for 0 ≤ θ < 2π. Give radians.

  1. Divide by 7.
  2. Find all unit-circle angles with the required coordinate equal to zero.
  3. Include 0 when valid; exclude 2π.

Answer: 0, π

Check your result using the method in the example before moving to the next question.
