Example- 1. "Good morning to all " is not a statement. 2. Every rectangle is a square" is a false statement.
  • Open statement - A sentence which contains one or more variable such that when certain values are given to the variable it becomes a statement, is called an open statement.

TRIGONOMETRY IDENTITIES

 TRIGONOMETRY IDENTITIES Calculation of trigonometric ratios for specific angles establish some identities are called Trigonometry identities. Or   can be say that an equation involving trigonometric ratios of an angle is called a trigonometry identity . SIN A = 1/COSEC A COS A = 1/SEC A TAN A = 1/COT A    OR      SIN A / COS A  COT A = 1/TAN A    OR      COS A / SIN A SEC A = 1/COS A  COSEC A = 1/SIN A COS 2  A+ SIN 2 A   = 1 OR SIN ²A + COS²A =1 SEC 2 A  - TAN 2 A   = 1  OR    1+ TAN 2 A   = SEC 2  A   1+COT 2  A= COSEC 2  AOR COSEC 2 A-COT 2  A=1 ADDITION AND SUBTRACTION Ø   SIN (A+B) = SINACOSB +COSASINB Ø   SIN (A-B) = SINACOSB – COSASINB Ø   COS (A+B) = COSACOSB – SINASINB Ø   COS (A-B) = COSACOSB + SINASINB Ø   TAN (A+B) =TANA + TANB/1-TANATANB Ø   TAN (A-B) = TANA-TANB/1 +TANATANB Ø   COT (A-...
