sin (A + B) = sinA cosB + cosA sinB
sin (A - B) = sinA cosB - cosA sinB
cos (A + B) = cosA cosB - sinA sinB
cos (A - B) = cosA cosB + sinA sinB
tan (A + B) = (tanA + tanB) / (1 - tanA tanB)
tan (A - B) = (tanA - tanB) / (1 + tanA tanB)
Double Angle Formulas:
sin 2? = 2 sin? cos?
cos 2? = cos²? - sin²? = 2cos²? - 1 = 1 - 2sin²?
tan 2? = 2 tan? / (1 - tan²? )
Triple Angle Formulas:
sin 3? = 3 sin? - 4 sin³?
cos 3? = 4 cos³? - 3 cos?
