Question

Phase shift, amplitude & period of:
y=(pi)cos(2x)+pi

Answer 1

didnt we do this already

Answer 2

it's up because I'm still confused

Answer 3

ok u need to understand what each number there does

Answer 4

tthe phase shift would be 0, presumably, amplitude would be pi. period would be...?

Answer 5

do you know how y=cos(x) looks like

Answer 6

dont worry about the words that really not htat important thats just english stuff

Answer 7

as long as you can picture how the graph looks like or you can draw the graph out thats good enough

Answer 8

i neeed it for an assignment, that's why.

Answer 9

i dont need to draw a graph

Answer 10

you get a 100/100 in my books if u can picture the graph in your head

Answer 11

T_T... the aim of these questions is to get you think about about the graph

Answer 12

ok look

Answer 13

lemme write it this way,
this is y=cos(x)
i can also write this as
y=1cos(1x+0)+0

Answer 14

this is what you are given now
y=picos(2x+0)+pi

Answer 15

can u see what parts of the normal cos(x) graphs are being changed now

Answer 16

im not blind - im just having issues

Answer 17

im talking about the graph

Answer 18

@Luigi0210 @chris00 @Jhannybean teach this guy

Answer 19

I don't need to be taught, i just need a simple answer. ><

Answer 20

the answer is already given to you, but u gotta understand it

Answer 21

look at our other post if u just want answer

Answer 22

.......

Answer 23

check out this really cool site that explains in details how to graph trig functions :)

Answer 24

I know how, I'm diabetic and we can't calculate things when we have a low blood sugar and I really just need to know the answer. Plan and simple.

Answer 25

Plain*

Answer 26

That's so off topic. :|

Answer 27

No, it's not.

Answer 28

We're here to guide you so YOU can find the answer :P not GIVE you the answer!! :)

Answer 29

listen man!! im trying to help you!! if u dont learn this now... one day u will get very and be like... oh math is actually fun i wish i had learnt more... and ur gonna be 50 and going back to school then

Answer 30

very old*

Answer 31

Fine then, I'll guess >.>

period = 2
Amplitude = pi
phase shift = 0

Answer 32

I'm going to school for astrophysics, I like math, just not functions lol

Answer 33

wut the...

Answer 34

what kind of astrophysics course is this

Answer 35

u want maths, come to my post. i'm like :|

Answer 36

your period is pi okay

Answer 37

the period of cos(x) = 2pi
so the period of cos(2x) = pi because the function will be going twice as fast

Answer 38

i did this in yr 11 i could help..if ya want

Answer 39

ah, so i was right before i started over analyzing.

soooo...
period =pi, amp = pi, phase shift = 0?

Answer 40

dont they teach you quantum physics for astrophysics?

Answer 41

So?

Answer 42

.. soo how can u not like math

Answer 43

i like math

Answer 44

south park:' screw this i'm going home'

Answer 45

im just in a rush & don't particularily enjoy this type of math

Answer 46

ok i see yes this isnt really math

Answer 47

i know what u mean bro. i didn't like it

Answer 48

how are you liking quantum mechanics tho

Answer 49

i have that after summer break

Answer 50

chemical engineering is the way to go guys. u hit the bids up.

Answer 51

chemistry is cool too buutt too much tedious stuff

Answer 52

I hear chemical engineering is hard ^ yea quantum mechanics is pretty epic.

Answer 53

chemical engineering is soo much work. got midsemseter exams in a week

Answer 54

i have an exam on the 19th :P i feel your pain
