1_INTEGRATION STRATEGIES

1. simplify

   • trigo identities
   • algebraic identities

2. substitution

3. identify

   • rational
     • use partial fraction
       • example
   • polynomial x trigo or exponential or log
     • use integration by parts
       • example
   • (sin x cos) or (sec x tan) or (csc x cot)
     • use identities
   • • trigo substitution
   • when , x > 2
     • substitution
   • quadratic
     • completing square

4. multiple techniques

   • use > 1 methods to solve a question

5. try

   • again & again until you get the answer !
