Answer 1

\[\sec(x)=1/\cos(x) \implies 1/\cos(x)=-1 \implies \cos(x)=-1 \implies x=\pi\]

Answer 2

thats the full thing?

Answer 3

so it is 3.14

Answer 4

or just pi.

Answer 5

are the => the greater than or equal to signs or are they showing the next step?

Answer 6

its an implies. I am replacing sec(x) with 1/cos(x) both of which are equal to -1. Then solving for x.

Answer 7

so if i were to write this down, showing my work, id leave out the => ?

Answer 8

If you're asking how to COPY my work, then I'm not answering...
