$\"\"$

Characteristic of a sinusoidal function :

Period $\"\"$ , Amplitude $\"\"$ and the point $\"\"$ .

The amplitude is $\"\"$ .

To find $\"\"$ , use the formula of Period $\"\"$ .

$\"\"$

$\"\"$ .

Since $\"\"$ and $\"\"$ ,the sinusoidal function is $\"\"$ .

The point is $\"\"$ .

Substitute $\"\"$ in the function $\"\"$ .

$\"\"$

Hence the fucntion $\"\"$ passes through the point $\"\"$ .

$\"\"$

Therefore ,a sinusoidal function with period $\"\"$ and amplitude $\"\"$ that passes through the point $\"\"$ is $\"\"$ .
