Trapezium Rule- finding area of region A.

  1. Apr 13, 2012 #1
    1. The problem statement, all variables and given/known data

    Question 2
    http://www.xtremepapers.com/CIE/International A And AS Level/9709 - Mathematics/9709_s11_qp_22.pdf

    2. Relevant equations

    A=1/2xh[(y1)+2(y2)+2(y3)....+(yn)]

    3. The attempt at a solution
    I know h=1
    x=0 y=1
    x=1 y=√2
    x=2 y=√5

    however when i plug this into equation, i get wrong answer.
    (.5)x1(1+2(√2)+√5
    i get 3.03 and the answer should be 3.41. :( what am i doing wrong

    nevermind i got it. it should be y=3 when x=2. i plugged it in wrong because i did x squared not cubed. calculation error
