Question

2sin((2/3)x -(pi/6))

Answer 1

y = Asin(bx+c)

amplitude = |A|
period = 2pi/b
phase shift = c

Answer 2

A:2
Period: 2pi/(2/3)
phaseshift: pi/6

Answer 3

Yes ! phase shift is pi/6 units to right

Answer 4

awesome

Answer 5

looks u nailed these :)

Answer 6

one last question for the night...

Answer 7

yes u may ask here

Answer 8

i hope so i have a huge test tomorrow

Answer 9

okies

Answer 10

u wil do great im sure

Answer 11

y= cos ((pi/2)-x)

Answer 12

i hope so !

Answer 13

we use this first : cos(-x) = cos(x)

Answer 14

y= cos ((pi/2)-x)

is same as

y= cos (x - (pi/2))

Answer 15

next do it exactly SAME as sin.

Answer 16

A:1
pasheshift = -1
period :4

Answer 17

NO. you need to look at the thing attached to variable \(x\)

Answer 18

y= cos ((pi/2)-x)

is same as

y= cos (x - (pi/2))
^^

Answer 19

A : 1
phaseshift : pi/2 rightside
period : 2pi/1 = 2pi
