WebHalf angle formulas can be derived from the double angle formulas, particularly, the cosine of double angle. For easy reference, the cosines of double angle are listed below: cos 2θ = 1 - 2sin2 θ → Equation (1) cos 2θ = 2cos2 θ - 1 → Equation (2) Note that the equations above are identities, meaning, the equations are true for any value of the variable θ. chop sister bay wiWebTwo angles are called complementary if their measures add to 90 degrees, and called supplementary if their measures add to 180 degrees.
