Question

.

Answer 1

most of them are right there in the equation, just pull them out .... period and phase shift are not difficult, but may be the hardest part

Answer 2

the normal period for cosine is at cos(2pi)

cos(2x) = cos(2pi), the value of x will tell us the adjusted period

Answer 3

and a phase shift, you need to factor the 2 from the setup and read the shift like a normal function

Answer 4

let me dbl chk the phish

2x + pi

2(x+pi/2)

x+pi/2 = 0 when x=-pi/2 looks good to me

Answer 5

i spose 2x+pi= 0 when x=-pi/2 would suffice, but its just too short to work with lol

Answer 6

prolly not. post a new question and see who bites
