I need help simplifying (sqrt(x^2-49))/(x) where x =7sec(theta)
I'm completely stumped, Trigonometry has proven to not be my strongest subject. Any help, or something worked out to push me in the right direction, would be fantastic!

sqrt(x^2 - 49)/x where x = 7 sec(theta)
sqrt(7(sec(theta)))^2 - 49) / (7sec(theta))
sqrt(49(sec(theta))^2 - 49)/ (7sec(theta))
sqrt(49[(sec(theta))^2 - 1]) / (7sec(theta))
sqrt{49(tan(theta))^2 / (7sec(theta))
(7 tan(theta)) / (7sec(theta))
7 tan(theta) cos(theta)/ 7
tan(theta) cos(theta)
sin(theta)/cos(theta) * cos(theta)
sin(theta)
