Question

Pre Calculus: The following data represents the normal monthly precipitation for a certain city.

Answer 1

info...... missing

Answer 2

yah hang on geeze lol

Answer 3

@xapproachesinfinity

Answer 4

Draw a scatter diagram of the data for one period. (You do not need to submit the scatter diagram). Find the sinusoidal function of the form  that fits the data. Show your work.

Answer 5

uh so now we have the data, we still do not have a question

Answer 6

i just posted it

Answer 7

ok, so can you plot the points?

Answer 8

sure hang on

Answer 9

kk

Answer 10

@FibonacciChick666

Answer 11

ok, so now, kind of looks like a sine curve right?

Answer 12

a what

Answer 13

a sine curve. Ya know sine, cosine, tangent...

Answer 14

how do you know the difference

Answer 15

what do you mean? The question tells us to use sine... sinusoidal=sine

Answer 16

no im just asking how you tell the difference between the differnt curves

Answer 17

uhm, graph them? tan and the others look nothing alike, sine/cosine are just a shift apart

Answer 18

you just pick one

Answer 19

but in this case we dont pick because it tells us to use sine

Answer 20

yep

Answer 21

but we have to modify the traditional sine curve to make it similar

Answer 22

I usually start with the y intercept and go from there

Answer 23

how do we do this

Answer 24

well, start by graphing an ordinary sine curve

Answer 25

then think about how you can move the curve around and make it look like our scatter plot

Answer 26

how do you graph that

Answer 27

so compare y intercepts first

Answer 28

uhh, you just graph it on your calculator....

Answer 29

i dont have a calculator

Answer 30

well, that's not my problem

Answer 31

you clearly have the internet

Answer 32

yes what kind of calculator do i need

Answer 33

....? You should have covered this in trig?

Answer 34

and btw im not stupid im actually very smart but for some reason my brain can comprehand anything the pre calculus or physics is all

Answer 35

Maybe you should just watch some khanacademy videos from the ground up

Answer 36

havent takin trig

Answer 37

it may just be crappy teachers

Answer 38

then how are you in pre-calc?

Answer 39

possibly could if i had teachers at all

Answer 40

I detest physics, so I get it. and no teacher?

Answer 41

yup just an online text book and a lot of assignments

Answer 42

well, that explains issues. You are missing some severely needed background information for this. So, let me get you the link for khan on this. He teachers better that me for this topic.

Answer 43

look im not trying to be mean but im not interested in learning at this point i havee two assignments left and i graduate so i just want to get it done

Answer 44

https://www.khanacademy.org/math/trigonometry/trig-function-graphs/trig_graphs_tutorial/v/midline-amplitude-period

So here is the deal, the video like 4 down tells you exactly how to do this, but in order to understand it, you'll need the first few

Answer 45

i self taught all my other subjects without help and passed with a overall 3.3 gpa by no means am i incapable i just dont have the time anymore. i turn 18 in a week and im out on my own which means i wont be able to do this anymore

Answer 46

I get graduating, I am too, but because of that and this being my procrastination, I just don't have the patience to guide you to the answer if you don't know what the sine graph looks like

Answer 47

There is to much missing background. This cannot be taught in one night

Answer 48

ik thats why i need an explanation for the answer i dont really need to understand it all

Answer 49

it needs like at least 3 hours unless you watch the khan videos, they are more concise

Answer 50

just watch it https://www.khanacademy.org/math/trigonometry/trig-function-graphs/trig_graphs_tutorial/v/trig-function-equation

Answer 51

ok
