**9.7 Evaluate the Integral**

Evaluate the integral 

\[ I = \int_{0}^{2.4} \frac{2x}{1+x^2} \, dx \]

using the following methods:

(a) **Simpson’s 1/3 Method**: Divide the whole interval into six subintervals.

(b) **Simpson’s 3/8 Method**: Divide the whole interval into six subintervals.

The exact value of the integral is 

\[ I = \ln\left(\frac{169}{25}\right). \]

Compare the results and discuss the reasons for the differences.
