Chapter 13.2, Problem 11OE

To determine

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

Answer to Problem 11OE

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

Explanation of Solution

Given information:

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

Calculation:

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

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

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