The General Sine and Cosine Functions
\[f(x)=A+Bsin(Cx-D)\]
and \[g(x)=A+Bcos(Cx-D)\]
.Thse are transformations of the functions
\[f_1(x)=sinx\]
and \[g(x)=cos x\]
.There are altogether four transformations for each funcyion - two
\[x\]
transformations and two \[y\]
transformations.The order of the
\[y\]
transofmations is important, and so is the order of the \[x\]
transfomrations, but either the \[x\]
or \[y\]
transformations may be performed first.1. Scaling in the
\[y\]
direction by a factor \[B\]
then translation in the \[y\]
by an amount \[A\]
.2. Translation in the
\[x\]
direction by an amount \[D\]
then a scaling in the \[x\]
direction by a factor \[C\]
.
