Chapter 13.2, Problem 13OE

To determine

To find: The complete the table by using positive or negative for each entry.

Answer to Problem 13OE

The trigonometric table will be positive, positive, negative and negative.

Explanation of Solution

Given information:

Angle	$\csc s$
$0<s<\frac{\pi }{2}$
$\frac{\pi }{2}<s<\pi$
$\pi <s<\frac{3\pi }{2}$
$\frac{3\pi }{2}<s<2\pi$

Calculation:

The trigonometry table from $0<s<2\pi$ by using positive or negative is given below

Angle	$\csc s$
$0<s<\frac{\pi }{2}$	$+$
$\frac{\pi }{2}<s<\pi$	$+$
$\pi <s<\frac{3\pi }{2}$	$-$
$\frac{3\pi }{2}<s<2\pi$	$-$

Therefore, the trigonometric table will be positive, positive, negative and negative.
