Answer ALL Questions.
1. Using a non programmable scientific calculator. Find the value of the following expressions.
  1.                                                correct to 5 decimal places

 
  1.     dx.

 
2. (a) Sets A, B and C are defined by
 

          A =     X E R:   -3 <  x  ≤ 2
 

          B =      X E R:  -4 ≤ x < 3
