Answer 1

Part A: One full cycle is completed in 2pi/9.

So you're trying to construct a sine function, \(\large\rm \sin(bx)\),
where \(\large\rm b=\frac{2\pi}{period}\)

Answer 2

Oh you figure them all out? c:

Answer 3

No lol

Answer 4

I tried ... so:\[b=\frac{2\pi}{period}=\frac{2\pi}{\frac{2\pi}{9}}?\]

Answer 5

looks good :) simplify!

Answer 6

o-o uh... 9? lol

Answer 7

I feel like that's wrong

Answer 8

yay good job \c:/

Answer 9

0.0

Answer 10

Okay... I have another one (posted above)

Answer 11

Any ideas? :)
Sine or cosine maybe?
and what's the period?

Answer 12

and what's the amplitude?

Answer 13

6cos(bx)

Answer 14

period appears to end somewhere between 2pi/5 and 3pi/5

Answer 15

The period will return you to the same location that you started at.
So if you're starting at the top,
then the end of your period will be at the top as well.

Answer 16

Oh. Right... ^^;

Answer 17

So then 3pi/5

Answer 18

Hmm looks like the curve is at the `bottom` at 3pi/5, ya? :o
Not the top as we're looking for.

Answer 19

Yes :p

Answer 20

So, no, not 3pi/5 for period.
