# Error Analysis In Exercises 33-36, use the error formulas to find bounds for the error in approximating the definite integral using (a) the Trapezoidal Rule and (b) Simpson’s Rule. Let n = 4. ∫ 0 1 1 x + 1 d x

(a)

To determine

To calculate: Find the bounds for the error in approximation for the integral 011x+1dx with the Trapezoidal Rule by using Error formula.

Explanation

Given Information:

The definite integral is 011x+1dx, and n=4.

Formula used:

Errors in Trapezoidal Rule:

If a function f is continuous on [a,b], then the errors E in approximating,

abf(x)dx

are as shown below,

|E|(ba)312n2[max|f(x)|], axb

Calculation:

Calculation to get error in the approximation of the integral:

Consider the definite integral 011x+1dx.

The double derivative of the f(x)=1x+1.

First derivative of f(x)=1x+1

f(x)=1(x+1)2

Second derivative of f(x)=

(b)

To determine

To calculate: Find the bounds for the error in approximation for the integral 011x+1dx with the Simpson’s Rule by using Error formula.
