SOLVED:Addition Formula for sine In the text we proved only the Addition and Subtraction Formulas for Cosine. Use these formulas and the cofunction identities sinx=cos((π)/(2)-x) cosx=sin((π)/(2)-x) to prove the Addition Formula for sine. [ Hint: To get started, use the first cofunction identity to write sin(s t) =cos((π)/(2)-(s t)) =cos(((π)/(2)-s)-t) and use the Subtraction Formula for Cosine. ]
