SHORT QUESTIONS AND ANSWERS

 

1. State Trapezoidal rule for evaluating . [A.U CBT A/M 2011]

Solution :

I = hk / 4  [(Sum of the values of ƒ at the four corners)

+ 2 (Sum of the values of f at the remaining nodes on the boundary) + 4 (Sum of the values of f at the interior nodes)]

 

2. State Simpson's rule for evaluating .

Solution :

I = hk / 9 [(Sum of the values of ƒ at the four corners)

+ 2 (Sum of the values of ƒ at the odd positions on the boundary except the corners)

+ 4 (Sum of the values of f at the even positions on the old boundary)

+ {4 (Sum of the values of f at odd positions)

+ 8 (Sum of the values of ƒ at even positions) on the odd row of the matrix except boundary rows}

+ {8 (Sum of the values of f at the odd positions)

+ 16 (Sum of the values of ƒ at the even positions) on the even rows of the matrix)}]
