Question

Identify the amplitude, phase shift, period.
y=sin(pi x+pi/2)

Answer 1

also if you could please sketch a quick graph for me thanks!

Answer 2

Amplitude is 1, phase shift is pi/2 i forgot how to do period

Answer 3

How you get that ? please explain

Answer 4

f(x)=asin(kx-d)
a=amplitude so in this case a=1
now the period = 2pi/k
k=pi so its 2pi/pi=2 so our period is 2
phase shift is our d
d= -pi/2 which is a horisontal translation of pi/2 degrees to the left

Answer 5

the standard equation is y=Asin(xtheta + k)

where A is the amplitude, x is the period and k is the phase shift

Answer 6

should be - k sorry but yeah what sam wrote down

Answer 7

So the standard equation is y=Asin(xtheta - k) right ?

Answer 8

Right
