- 1ADDITION FORMULA : SINESIN(A + B): SINACOSB + SINBCOSA
SIN(A - B): SINACOSB - SINBCOSA - 2ADDITION FORMULA: COSINECOS(A + B): COSACOSB - SINASINB
COS(A - B): COSACOSB + SINASINB - 3ADDITION FORMULA: TANTAN(A + B): (TANA + TANB) / (1 - TANATANB)
TAN(A - B): (TANA - TANB) / (1 + TANATANB) - 4DOUBLE ANGLE FORMULA: SINESIN2A: 2SINACOSA
- 5DOUBLE ANGLE FORMULA: COSINECOS2A: COS^A - SIN^A
= 2COS^A - 1
= 1 - 2SIN^A - 6DOUBLE ANGLE FORMULA: TANTAN2A: 2TANA/(1 - TAN^A)
- 7OTHER IDENTITIES USING COSECX, SECX AND COTXCOS^X + SIN^X = 1
1 + TAN^X = SEC^X
1 + COT^X = COSEC^X
