What is the value of sec 0?

          %sec(0) = 1%                                    <h4 class=answerHeader>Explanation:</h4>                                      Knowing the property:<br></br><mathjax>%sec(theta) = 1/cos(theta)%</mathjax>Here <mathjax>%theta = 0%</mathjax>,So, <mathjax>%sec(0) = 1/cos(0)%</mathjax><br></br>Substituting <mathjax>% cos(0) = 1%</mathjax>.  we have:<mathjax>%sec(0) = 1/1 %</mathjax>     Therefore, <mathjax>%sec(0) = 1%</mathjax>
