Characteristics of a sinusoidal function :
\Period , Amplitude
and the point
.
The amplitude is .
To find , use the Period
and the function is Period
.
Since and
,the sinusoidal function is
.
The point is.
Substitute in the function
.
Hence the fucntion passes through the point
.
A Sinusoidal function with period and amplitude
that passes through the point
is
.
