Consider the definite integral
$$\int_{1}^{2} \left ( 4x^{2} + 2x + 6 \right )dx.$$
Let $I_{e}$ be the exact value of the integral. If the same integral is estimated using Simpson’s rule with $10$ equal subintervals, the value is $I_{S}$. The percentage error is defined as $e = 100\times \left ( I_{e} - I_{S}\right )/I_{e}$. The value of $e$ is
- $2.5$
- $3.5$
- $1.2$
- $0$
