The amplitude of the function is $\"\"$ and period is $\"\"$ .

\

The phaseshift of the function is $\"\"$ .

\

Find the equation of a sine function.

\

The genreral form of sine function is $\"\"$ .

\

Where the amplitude is $\"\"$ ,period is $\"\"$ and phaseshift is $\"\"$ .

\

The amplitude is $\"\"$

\

The period is $\"\"$ .

\

$\"\"$

\

$\"\"$

\

$\"\"$

\

Phaseshift is $\"\"$

\

$\"\"$

\

$\"\"$

\

Substitute $\"\"$ , $\"\"$ and $\"\"$ in $\"\"$ .

\

Therefore, the equation of the sine function is $\"\"$ .

\

\

The equation of the sine function is $\"\"$ .
