y=2secx

OpenStudy (mertsj):

y=2/cosx

OpenStudy (anonymous):

what?

OpenStudy (anonymous):

but de equation

OpenStudy (mertsj):

Exactly

OpenStudy (anonymous):

ok but y=2/cosx

OpenStudy (anonymous):

??

OpenStudy (anonymous):

What exactly are you supposed to do? Solve for x?

OpenStudy (anonymous):

-rad/3<X<rad/3 and 5rad/3 <X<7rad/3

OpenStudy (anonymous):

x

OpenStudy (mertsj):

The problem is, giovana, that you never asked a question.

OpenStudy (anonymous):

ok

OpenStudy (anonymous):

i need y

OpenStudy (anonymous):

If so, then you could go further from y=2/cosx to... y/2=1/cosx cross multiple to get... cosx = 2/y then... x = cos^(-1)[2/y]

OpenStudy (anonymous):

you wrote \[y=2\sec(x)\] but there is no question here. you already have y, \[y=2\sec(x)\]

OpenStudy (anonymous):

the question could be something like 1) graph 2) evaluate if x = some number 3) find the domain something of that sort. an equation is not a question

OpenStudy (anonymous):

What did you mean by "-rad/3<X<rad/3 and 5rad/3 <X<7rad/3" ? Is that the domain this is bound in? What does rad mean?

OpenStudy (anonymous):

2

OpenStudy (anonymous):

rad

OpenStudy (mertsj):

y depends on what x is. You cannot tell what value y has unless you specify a x value

OpenStudy (mertsj):

Why don't you post the directions.

OpenStudy (anonymous):

=/

OpenStudy (anonymous):

@giovana there are a lot of people here anxious to help you, but you really need to ask a question \[y=2\sec(x)\] is not a question, it is just an equation. like \[y=x^2\] or \[y=\frac{1}{x}\]
