  1. Mathf4et121p2qn22a
    x2/2 + 2/3x3 + c
     
  2. The exact area bounded by the curve, x axis 
    x= -½ and x=3 (Give your answer to 2dp)
    MathfRM4et121p2a22
    =0-(1/8 – 1/12)
    - (3-2)
           24
    = - 1/24 ∴ 1/24
    32/2 + 2/3 x 33 __(0)
    9/2 + 54/3
    4.5 + 18 = 22.5
    Total area = 1/24 + 22.5=0.0416 + 22.5
    = 22.54
