Question

what is the phase shift of y= 3cos(6x+ pi/2)

Answer 1

pi/2

Answer 2

be careful here

Answer 3

if you want to read the phase shift from the formula it needs to look like
\[A\cos(B(x-c))\] not
\[A\cos(Bx -c)\]

Answer 4

if you really want to graph this thing it is the same as
\[-3\sin(6x)\] which it a lot easier to figure out. but to find the phase shift you will need to write it as
\[3\cos(6(x+\frac{\pi}{12})\]

Answer 5

so it would be \[\Pi/12\]

Answer 6

yes

Answer 7

thank you

Answer 8

yw

Answer 9

but i repeat it would be much easier to graph
\[y=-3\sin(6x)\] where the amplitude is 3 and the period is
\[\frac{\pi}{3}\]

Answer 10

then to try to figure out what this looks like from the period and the phase shift.
