Solution
We have given Amplitude =7,period =5pi and Phase shift=-1/3
y=Asin(Bx-C) where A is Amplitude,period =2pi/B and Phase shift=C/B
for give A=7,5pi=2pi/B and -1/3=C/B
B=2pi/5pi=2/5
substitute B into -1/3=C/B
C/(2/5)=-1/3
C=-1/3*2/5=-2/15
y=Asin(Bx-C)
y=7sin((2/5)x+2/15) since A=7,B=2/5,C=-2/15
