5.3 Sinusoidal Functions of the Transformation Form..!!

The transformation of a sine or cosine function f(x) to g(x) has the general form g(x) = a f ( k(x - d) ) + c, 
where :

• a is the amplitude.
• d is the phase shift 
• c is the vertical translation

The period of the transformed function is given by 2π
