Solve the following equations for all values of x in the domain [0, 2π). Use exact values. Homework Help ✎

  1. sin(2x) = sin(x)

    sin(2x) = 2sin(x)cos(x). Substitute and solve for x.

    There will be four solutions.

  2. sin(x + π) + cos = 1

    There is no solution to this problem.

  3. cot(x) – tan(x) = 2

    There will be four solutions.
