Question

what is the value of sec theta

Answer 1

Step-by-step explanation:

$\huge\underline\purple{\mathcal Answer :-}$

the equation sec(theta)=-1 turns to 1/cos(theta)=-1, which is equivalent to cos(theta)=-1. The only values of theta that satisfy this are theta=pi +2k pi for k in ZZ. If you prefer the notation with degrees: theta=180°+360°k for k in ZZ.

Answer 2

$\huge\sf{Answer:-}$

theta = π +2k π
