i need it step by step to understand it

here it is when i pasted it to google.

i got 6.995735789x

.64 i suppose.

idk about that with google i got .64

use function manipulation

step bu step if you could

so whats next then

yup with you

according to your info 3:30 is high tide.
we can call that 3.5

so whats the next step to this problem

Using 20*sin(x)+32 we have to get the hide tide to occur at 3.5 we shift it
20*sin(x-a)+32

so should i erase sin and use cos

so 20*cos(x-3.5)+32 is the final answer

yup did you understand? :)

yes thank you very much for all that help

let me know if it is correct

okay

its okay

there is also the odds that i need to stretch it horisontally

oh yup you do have to stretch
