Question

Could anyone help with this activity I have to do? It's trigonometry

Answer 1

I'd really appreciate it if someone could explain so I can figure it out . I'm terrible at trig . I'm taking an algebra 2 class and apparently trig is apart of algebra 2

Answer 2

@jim_thompson5910 could you help me with this ? :/

Answer 3

Your worksheet is a bit misleading. It says that B = 2pi/(period) but that's only true for sine, cosine, cosecant, secant. It doesn't apply to tangent and cotangent. That rule would be B = pi/(period). Luckily we won't be dealing with tangent or cotangent

Answer 4

did I write that ?

Answer 5

no it's printed on page 1

Answer 6

apex is confusing and doesn't do the right information

Answer 7

doesn't give *

Answer 8

you wrote the correct max elevation

what is the min elevation?

Answer 9

it didn't give that . Idk

Answer 10

since the ride starts 10 ft off the ground

Answer 11

oh so it'd be 10 ? lol

Answer 12

yeah

Answer 13

and that would make the diameter 210 - 10 = 200 and not 210

Answer 14

I have the diameter as 200

Answer 15

oh nvm I misread that part

Answer 16

don't forget the units. When it asks for the time to complete 1 revolution. Don't just write "90". Write "90 seconds". Same applies for the other values too

Answer 17

other than that, page 1 looks great

Answer 18

do the max and min have units ? oh and the diameter ?

Answer 19

yeah, in this case, "feet"

Answer 20

same for the diameter

Answer 21

okay I just wanted to be sure

Answer 22

ready for #2 ?

Answer 23

yes

Answer 24

I'm guessing you haven't started at all? Or do you have an idea where to start?

Answer 25

The graph is where I got confused . I looked over it multiple times and I tried graphing but I just didn't understand

Answer 26

At time t = 0 seconds, the height is h = 10 ft

So one ordered pair is (0,10) and this is a min

--------------------------------------

45 seconds later at t = 45, the height moves to h = 210

one max point is (45,210)

--------------------------------------

another 45 seconds pass by and we're now at t = 90 seconds

we're back at the min height again and now at the point (90, 10)

Answer 27

they want you to plot these mins and maxes for 2 full cycles

Answer 28

I always forget how to graph lol . Just one second

Answer 29

For #2, they don't want the full graph of the sinusoidal curve (ie they don't want sine or cosine plotted). They just want those discrete points.

Answer 30

so don't plot all three of those points ?

Answer 31

You do plot those points and any others that I didn't list until you've done 2 full cycles

Answer 32

If you start at t = 0,

1 full cycle ends at t = 90
2 full cycles end at t = 180

Answer 33

so it'd look somewhat like that ?

Answer 34

that's a horrible drawing I know lol . My mousepad sucks

Answer 35

that's ok. You should get something like this (see attached). It looks like you did, so you are correct for #2

Answer 36

do I connect the dots or leave them as is ?

Answer 37

For #2, they just want the min/max points. That's all. So you leave them as is.

Answer 38

Okay so that one is done

Answer 39

what did you get for #3

Answer 40

I'm reading it right now

Answer 41

wouldn't the top of the ferris wheel be the max ?

Answer 42

yes

Answer 43

so it'd be 210 ?
