2. Start with sin(x)        amplitude is 1      want 4   so multiply by 4

     4 sin(x)                    period is 2 pi     frequency is 1/2pi     want period = 4     frequency = 1/4

                                         1/2pi * m  = 1/4       m= modulator    

                                          m= 2pi/4 = pi/2

4 sin (x pi/2)

 

AND shift it up 1....just add 1

 

4 sin (x pi/2)  + 1
