Chapter 4: Q. 50 (page 353)

Calculate the exact value of each definite integral in Exercises 47–52 by using properties of definite integrals and the formulas in Theorem 4.13.
$\int_{1}^{3} (x + 1)^{2} d x$

Short Answer

Expert verified

The exact value of definite integral is $\frac{56}{3}$ .

Step by step solution

Step 1. Given Information

We are given,

$\int_{1}^{3} (x + 1)^{2} d x$

Step 2. Finding the Integral

The definite integral is given by,

$\int_{1}^{3} (x + 1)^{2} d x = \int_{1}^{3} x^{2} + 2 x + 1 d x = \int_{1}^{3} x^{2} d x + 2 \int_{1}^{3} x + \int_{1}^{3} d x = \frac{1}{3} [3^{3} - 1] + 2 (\frac{1}{2}) [3^{2} - 1] + [3 - 1] = \frac{26}{3} + 8 + 2 = \frac{26 + 24 + 6}{3} = \frac{56}{3}$
