- 
					 The definite integral
 is evaluated using trapezoidal rule with a step size of 1. The  correct answer is  ________.   
- 
                        
- 2.1667
 - 1.957
 - 2.114
 - 1.1667
 
 
Correct Option: D
| Given : ∫³1 | dx | |
| x | 
h = step size 1
n = no. of sub intervals
| = | = 2 | |
| 1 | 

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