Chapter 13.2, Problem 10OE

To determine

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

Answer to Problem 10OE

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

Explanation of Solution

Given information:

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

Calculation:

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

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

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