oh. gotcha

anyways, I think I figured it out

okie

so gimme a second

i solved it but what is ur answer

oh, nvm

i dont know how to get the actually number -_-

i got point o

points d, c, p, and o go through it

this makes it easier to understand

i drew it out

the problem is from the International Math Olympiad

here is another one

i havent solved this one yet so idk the answer

ye, thats about the extent to which I figured it out. Just didn't have any of the values figured out.

the answer to that one is

oh that one dosent have a backround

ill just type it

those are the steps

after I got the answer it gives u the explanation

Need help

i might be able to help

Thank you

so is the first one this? -2+.5*cos(8x+(2pi/3)

the -2 is the vertical shift

the .5 is the amplitude

8 affects the period

and 2pi/3 is the phase shift
