Write the equation of a sine function that has the following
     Write the equation of a sine function that has the following characteristics.  Amplitude: 4 Period: 5 pi Phase shift - 1/5  Type the appropriate values to complete the sine function.  y =  sin (x +) 
  
  Solution
Amplitude:4 period :5pi phase shift:-1/5
The sine function is of the form
y= A sin(Bx+C)
where amplitude is A, period is 2pi/B and phase shift is -C/B
Comparing it with given values ,we get A=4, 2pi/B= 5pi
B:2/5
phase shift -C/B =-1/5
-C/2/5=-1/5
C= 2/25
required sine function is y= 4sin(2x/5 +2/25)
