Chapter 5: Q. 37 (page 417)

Solve each of the integrals in Exercises 21鈥�70. Some integrals require substitution, and some do not. (Exercise 69 involves a hyperbolic function.)
$鈭� x^{4} {(x^{3} + 1)}^{2} d x$

Short Answer

Expert verified

The solution of the given integral is $鈭� x^{4} {(x^{3} + 1)}^{2} d x = \frac{1}{11} x^{11} + \frac{1}{8} x^{8} + \frac{1}{5} x^{5}$ .

Step by step solution

Step 1. Given Information

Solving the given integrals.

$鈭� x^{4} {(x^{3} + 1)}^{2} d x$

Step 2. Solving the given integral using algebra.

$鈭� x^{4} {(x^{3} + 1)}^{2} d x = 鈭� x^{4} {{(x^{3})}^{2} + 2 路 x^{3} 路 1 + {(1)}^{2}} d x 鈭� x^{4} {(x^{3} + 1)}^{2} d x = 鈭� x^{4} (x^{6} + 2 x^{3} + 1) d x 鈭� x^{4} {(x^{3} + 1)}^{2} d x = 鈭� (x^{4} 路 x^{6} + 2 路 x^{4} 路 x^{3} + x^{4} 路 1) d x 鈭� x^{4} {(x^{3} + 1)}^{2} d x = 鈭� (x^{10} + 2 x^{7} + x^{4}) d x$

Step 3. After simplifying

$鈭� x^{4} {(x^{3} + 1)}^{2} d x = 鈭� x^{10} d x + 2 鈭� x^{7} d x + 鈭� x^{4} d x 鈭� x^{4} {(x^{3} + 1)}^{2} d x = [\frac{x^{10 + 1}}{10 + 1}] + [\frac{x^{7}}{7 + 1}] + [\frac{x^{4 + 1}}{4 + 1}] 鈭� x^{4} {(x^{3} + 1)}^{2} d x = \frac{x^{11}}{11} + \frac{x^{8}}{8} + \frac{x^{5}}{5} 鈭� x^{4} {(x^{3} + 1)}^{2} d x = \frac{1}{11} x^{11} + \frac{1}{8} x^{8} + \frac{1}{5} x^{5}$
