  1. The definite integral is evaluated using trapezoidal rule with a step size of 1. The correct answer is ________.
    1. 2.1667
    2. 1.957
    3. 2.114
    4. 1.1667
Correct Option: D

Given : ∫³1
1
dx
x

h = step size 1
n = no. of sub intervals
=
3 - 1
= 2
1


By trapezoidal rule
xnx0 f(x) dx = h/2[(y0 + yn) + 2(y1 + ...........+ yn-1)]
