Question

write the equation of the sine function
Amp:4 Period: 5 PI Phase Shift: -PI/5

Answer 1

y = 4sin(2theta/5 - pi/50

FINDING B:
p = 2pi/b
5pi = 2pi/b
5pi/2pi = 1/b
2/5 = b

Answer 2

Thanks, was there a trick to it...I mean finding a number to use to get your -c/b?

Answer 3

Not really, just plugging in variables to known equations for a sign function
period = 2pi/b
y = Ampsin(Btheta +/- C) +/- D
was that phases shift in the y or x direction?

Answer 4

y

Answer 5

ooh then its gonna be: \[Y = 4\sin (2\theta \div 5) - \pi \div 5\]

Answer 6

Thanks so much!
