Identify the period, phase shift and vertical shift of 
y=-5sec (x+pi/3).  (if applicable)

PLease help

anonymous · Answer

@primeralph please help me?

primeralph · Answer

Period is 2pi as obvious.
Phase shift is +pi/3
Vertical shift (Amplitude, I guess) is -5.

anonymous · Answer

ahhh thank you!!! one more?

anonymous · Answer

Identify the period, phase shift and vertical shift of 
y=-4csc (2x).

primeralph · Answer

Try.

anonymous · Answer

okay

primeralph · Answer

Show me what you get.

anonymous · Answer

pahse shift is 2x
period is 2pi
vertical shift is 4?

anonymous · Answer

is that completely wrong? im sorry, I tried

primeralph · Answer

Yes. Completely wrong.

anonymous · Answer

dang it

anonymous · Answer

I really did try

primeralph · Answer

Phase shift is the k in Af(bx + k). In this case, -4csc (2x) = -4csc (2x + 0) because there is nothing added like in the other example, so phase shift = 0.
Period is 2pi/b = 2pi/2 = pi

primeralph · Answer

Looks confusing now, I know. Try to get some rest.

primeralph · Answer

Vertical shift is A, meaning -4.

anonymous · Answer

you're right. very confusing. thank you so muchthough
