Question

what is the value of sec minus theta

Answer 1

sec(-x) = sec(x) thk hh

Answer 2

Answer:

θ  =π+2kπfor k∈Z

Step-by-step explanation:

In college sports, the SEC is the Southeastern Conference. It is one of the NCAA Division I conferences.

It is a Greek letter which is used to mark an unknown angle in a triangle when you are going to use trigonometry to work it out, eg. sin(theta)=length of opposite side/ length of hypotenuse

If you remember some foundamental values for cosine, you can also avoid tables and work with the definition of the secant function, which is

sec

(θ):=1cos(θ)

Then the equation  

sec

(θ)=−1turns to 1cos(θ)=−1

, which is equivalent to  

cos(θ)=−1.

The only values of  

θ

that satisfy this are  

θ=π+2kπfor k∈Z

. If you prefer the notation with degrees:  

θ=180°+360°k

for  

k∈Z

.
