Short Answer

Expert verified

Ans:

鈭� \frac{1}{x^{2} - 4 x + 13} d x f o r 53 鈭� \frac{1}{\sqrt{x^{2} + 9}} d x f o r 56 鈭� \sqrt{x^{2} - 8 x + 25} d x f o r 57

Step by step solution

Step 1. Given information:

$x = a \tan u$

Step 2. Finding the three integrals using trigonometric substitution :

The three integrals that can be solved using a trigonometric substitution of the form $x = a$ tan $u$ are the exercises 53,56 and 57.

The integrals are as follows.

53. $鈭� \frac{1}{x^{2} - 4 x + 13} d x$

56. $鈭� \frac{1}{\sqrt{x^{2} + 9}} d x$

57. $鈭� \sqrt{x^{2} - 8 x + 25} d x$
