\

The given trigonometric equation is $\"\"$ .

\

Compare the equation is $\"\"$ , So A = 1, $\"\"$ .

\

Amplitute is $\"\"$ .

\

Then Period is $\"\"$ .

\

Horizontal shift is $\"\"$ .

\

Phase is $\"\"$ .

\

$\"\"$

\

To verify the period and horizontal shift, and sketch the graph by one cycle.

\

One cycle: $\"\"$

\

$\"\"$ (Add $\"\"$ to each side)

\

$\"\"$

\

$\"\"$ (Multiply each side by 2) $\"\"$

\

To graph of the trigonometric equation is $\"\"$ .

\

$\"graph$

\

$\"\"$

\

The Amplitute is 1, Period is $\"\"$ , Horizontal shift is $\"\"$ , Phase is $\"\"$ .
